Why is EVERY adult constantly breaking my Child Sim's dollhouse?

I have a doll house at every sims house that has kids and I have never once had one broken. I always put them outside because they are so big but that shouldn't make any difference, unless thay just don't want to go outside to smash them.

I don't usually put dollhouses in my sims houses. I did once, and the household members never smashed the dollhouse, however, when the parents' friends were over, the dollhouse was constantly broken until I eventually locked the door. I suspect one of their friends had the evil trait or something like that.

My sim is a hot head and has a habit of breaking his daughter's doll house when he's in a confident or playful mood. He has yet to make his daughter cry because he or his wife usually repair's it before she sees the damage. :D
