Ok so what inspired me to make this mod:

I was getting sick of my good sims getting into screaming matches with their mean family members so i wanted to use the parenting socials to tell them off instead without having to perform mean socials and thus lower their empathy and conflict resolution stats, getting them into angry moods and losing relationship points.

So now when my (Adult) sims evil (Adult) brother starts being mean, i get her to tell him off instead, it stops him in his tracks and is funny to see

This is a simple override that basically just opens up the discipline socials on the pie menu for all ages
It does't open the other parenting socials, just the discipline ones

Sims can now discipline any other sim including NPC's
Adults can also be sent on time out - they even get the time out buffs
I haven't unlocked ground for adults so if you want it then let me know and i'll see if i can add it in

I don't know if it affects adult stats as it doesn't show them increase or decrease like teens and children and the hidden buffs only say if they are high or low
I'll keep and eye on their hidden buffs and see

Teens can only use the calm or strict socials on adults - let me know if you want the others for them and i'll see if i can add them in

Conflicts: I haven't found any yet but most likely would conflict with any mod that edits the same resources i.e. other parenting mods

I got the idea from LittleMsSams Teen Parenting Mod
This is not a copy of that mod or any of the resources in it. It does use some of the same resources so may conflict with that one)
