Doesnt have to be immediate family either. Aunts, uncles, cousins, grandparents, whatever. I have a couple of aunts who are certifiably mental. One of them chops off all her hair with scissors and buys wigs to cover up her butchery. She cant stop cutting it off either, she has some irresistable internal urge to do so. She buys those, what she calls "cheap speeders" from gas stations like "yellow jackets" or whatever and eats them by the handfull and stays up for days on end. She also smokes crack, and left her husband for a drug dealer. But her husband is worthless, and ended up moving in with she and the drug dealer. She has two teenage daughters who live with their friends/boyfriends. I havent seen the woman in 10 years at least, thankfully, but get the odd update from my dad.
