My teacher had a saying,"Don't lend money unless you're okay with not getting it back."According to my parents, I'm ungrateful because I'm afraid if I give them $1500, they won't pay me back. They act like if they borrow it for this deposit, then they don't have to pay me back so apparently I'm ungrateful........
I'd lent $20 to my sister since I didn't care. You're parents sound less than perfect so if you do lend money, I wouldn't expect it back.
