alright so here it is, a good friend of mine sucks at saving money, and he keeps asking me to loan him $100 and he'll pay me back. im in the militart so i work hard for my money and good at saving. i have to fork out $635 for my truck cuz the a/c crapped out, and the last time i loaned him the same amount, he never payed me back. when i kept asking him he kept getting an attitude, weve been friends for over 8 years and hes like a brother to me, what should i do??
