If townies steal the food then they should totally be on the hook for the bill!

"That "random guy" you are trying to kiss is your cousin's fiancee."
"That girl dropped out of college. She doesn't go there. She just came by to see your cousin. Because she is pregnant with his child. So, maybe. Just maybe flirting with her is not the best idea"
"Thanks for that first woohoo cut scene. Great timing. Props for choosing someone your cousin doesn't even know."

Tazama McCallister had an eventful and educational first rotation in college. He even managed to go to one class!

"She's pregnant?! Girl...." to my sim who I didn't realize was pregnant

"That's a terrible idea, Bill. On the other hand -- you do have pointed ears."

(Elder Pleasure sim living with his son's family (including four grandchildren) in a house with only one room for one double bed, on a date with Jan Tellerman, rolled the want to get engaged to her three times. But I gave him pointed ears and the Romance son who got them can't seem to knock anybody up. So, you know, what's a bad idea in the service of spreading the weird genes? No, I didn't. But I might next time.)

"I have to stop making townies playable."
I say as another one moves in.

(I like townies. They just tend to come with friends, and their friends turn into playables as well, and I don't like when the neighborhood gets too big.)

I love NPCs. I free them from the suppression field of the chamber of commerce that keeps the hostage and working without rest. Last time I liberated the food stand NPC. Before that I liberated the register clerk to allow her to eat and use toilet. They come to visit. They come shopping. I made a restaurant run by an NPC family with a host, cook, bartender and server, and new young adult NPCs who work in University. They have beautiful heads made in body shop.

When I make a friend with an NPC, there is a long delay as his family friends are being counted for the career tab.

How did you do that? My food stand workers error out if there's no food stand.

Meanwhile in my games...

Sim: "Hey, Player; I brought this Sim home from work! They say they are a 'townie' and I'd like to be friends with them!

Me: "No. Nooo. Nooo. They're what's called an "extra". They can't join the storyline, because the screen actors guild forbids them from having speaking roles. So let's send them back to the land of winds and ghosts they spawned from :-)"
(there is only the very rare exception to this, like Kaylynn Langerak)

There are two babies on the way...
"Wait -- you didn't have any cheesecake! I don't think you had any cheesecake..."

Next house. There are two babies on the way...
"Again?"

Next house:
"Well?"
There is a new baby on the way!
"Whew!"

I treat the default Pleasantview townies as "extras" or test subjects. But custom made townies have a soul.

I had Mary-Sue Pleasant reach for a cheesecake autonomously in another household. I like making the cheesecake, how neat it looks. I had to stop her from grabbing it fast because she is not a twin material. Would you realistically know if two babies were coming beforehand? Is a woman noticeably bigger?

I mean you would see it on the ultrasound, but as far as I've heard people were often surprised in the days before those.

She might have the twin token anyway. There's history. XD

In Sims? No, the belly is the same size for one, two, (three or four w/triplets&quads mod).
You can check the pregnancy status with a mod (many different). They only detect single and twins (all multiples register as "2" babies).

Oh I never use the default townies. I always create my own. I even have a downloaded version of Pleasantview that has all townies and service NPCs removed, except for Kaylynn Langerak and Gordon King. But I still treat them as extras :-P

It's just that since I like to play many families rotationally, I usually have enough playable Sims to fulfil all needs they have for friends, romances, and promotions without bringing in townies. Even if, let's say, a Sim can't find a spouse I just create a new family the spouse can originate from, or create a spouse they can meet at college, rather than have them marry a townie.

I think I have two reasons for this; I don't have full control over the townies, like I have with playable Sims, and I don't want the game to create new townies when I deplete the pool of existing ones (probably one of those habits I still have from the early Sims 2 days and all the stuff that was said about character limits and game corruption)

No, I meant about real life twins. I know most of what there is about game twins.

I have a practical consideration too with how I treat townies and NPCs. They are always there no matter what, occupying memory. But they are not fleshed out in vast majority of cases (except downtownies). So if I add a personality to them, I replace the empty placeholders with something more unique without using much more data.

I usually don't marry them or otherwise take them out of the townie families, because my goal was to have fleshed out NPCs. I have moved out 2 townies/NPCs in my current neighborhood. People who build a romantic connection with an NPC are not of a family aspiration, and are content with dating the other person while he lives remotely. Since I always use the elixir of life, I assume that the townies also do, and it is therefore ok for them to remain unchanged. People try to make friends with local NPCs who work in the current neighborhood.

Kaylyn Langerak is an oddball case, since she has a (failed) family aspiration. So why do you like Kaylinn and Gordon King? Because they have some unique properties and connections. So it would be better if more of them were like this.

That depends on a variety of factors including, but not limited to, where the fetuses are located in the uterus/pelvis, the size and gestation of the fetuses, the amount of amniotic fluid present, and the physical size of the mother's torso. That said, there are also lots of singleton babies whose mothers may appear larger or smaller for the same reasons as well.

"Who knew Garden club members were great at fighting off zombies?"

I'm suddenly reminded of a TV series. One of the characters was a small woman, and towards the end of her pregnancy, her belly had expanded to terrific proportions. Granted, that was fiction, but all the same, it was easy to believe she was expecting twins.
"Wow, she's huge."
"Yeah, best not to mention that to her."
"You know, an elephant has a gestation period of 22 months."
"Yeah, best not to mention that, either."

Good heavens, imagine if the Sims games had a pregnant sim's belly size depend on how many babies she was pregnant with, or have a degree of randomness to it. Knowing the nature of the franchise, with how things are sometimes exaggerated, a sim carrying multiple children might have similar proportions to that character. In Sims 3 and 4, perhaps they'd even have negative moodlets like 'Moons Orbiting Me' or 'Sick of Being Pregnant'.
But then again, if they really wanted to flesh out the experience of being pregnant, sims would have more than increased motive drain, food cravings, and sore back moodlets. There would be moodlets about swollen feet, hip pain, and heartburn. Sims might have insomnia in the later stages, because the moment they lie down to rest is when the baby puts on their boxing gloves and starts practicing to be the next Muhammad Ali. There would be a chance of the sim having a pregnancy where the kid is doing a tap dance on their bladder towards the end. And the pregnant sim would be more emotional at times.

I was thinking that if it was visible or feelable, the person could pop up some indication like a thought balloon about twins.

One of my old school friends is 157cm tall, and her waist circumference exceeded her height at the end of pregnancy, when she had her twins.

Pregnancy sounds terrifying. I'm surprised the human race has bred as much as they have!

"Ok, so the connection between the two of you feels electric. Cute. Still no way I am gonna let you get struck by lightning together. No shared near death experiences on the first date."

Two young knowledge teens on a date during thunderstorm. Both rolled a want to be struck by lightning (and to make out, I suppose, during the striking). And they say the romance is dead.

Maybe it just needs a spark!
