What's your favorite part about The Sims 3?

I guess I can say that I can delete the schools, I have been playing the sims from sims 1 and I have always deleted schools, it does not affect my sims at all. I like the kids to stay home and play with them. It seems if they go to school, then they come home and do homework eat and go to bed. I guess I also like that I can play with them anyway I like. I love the Sims. Sims 3 is my favorite.
