Building subtle signs of abuse into my Sims' home

I created a mother-son pair and decided that his mom is narcissistic and controlling. I designed the house to show subtle signs of their dynamic. His room is decorated the exact same as hers because he gets no say in his own style. I put a worn patch on the wall behind the door because she slams it open so often. There is one bathroom and he has to go through his mom's room to get to it. There are no bookshelves in the house even though he is a bookworm and his homework desk is in the living room. The mom has her own computer that is locked for him and I placed his diary in her room which he will have to hide.

If you were to do a similar project, what details would you include?
