School Dances Event
You'll need however a chaperone to keep an eye on them during the party ;) You can have up to 3 of chaperones and they need to be at least teenagers.
Main guests are of course children. You can invite any child, you don't need to know them.
There is no real host of the party. You can be a chaperone even if you don't have kids (this opens actually possibility for Sims that are teachers and can have new responsibility after the work).
You can also hire a DJ - if you have Get Together expansion, and a caterer.
Your kids will be in extremely good mood after the party. But you can't say the same about the chaperones...
But you can choose a NPC for a chaperone so all is good :D

This mod doesn't override existing files so should not conflict with other Sims 4 mods.
