[Death by Mirrors]

Not Sims 4 but 3: one of my favorite families consists of a drunkard who lives on a house boat and doesn't give shit about his two daughters. The older one is a teenager who tries to look after her kid sister. Both get frequently locked out of the house, spend the night somewhere outside camping and making plans to build their own small cabin to live independently from toper dad. It's a small (custom) island neighbourhood too, so once the sisters grow up there won't be many jobs around and it pays off to be self sufficient.
