My SIL literally has nothing going for her and it's hard to watch. She's 19 she doesn't have a drivers license, she isn't working or in school, she doesn't cook or clean, or do her own laundry, she never goes out, she has no friends, she doesn't leave the house. Idk why her parents allow this. It's like they expect some guy to marry her and take her away but that's not gonna happen when she's a bathroom hogging couch potato.
