Well, if the person is dead broke, then there's no way you're gonna get your money back. I don't loan anyone any money because when you ask for it back, you have to beg them for your own money and your lucky if you get it back. So I just never lend them any money to start with.

Someone owes me some money, and I always have a hard time bringing it up and ironing out precise terms. It's not something I can go to court over, and the guy is probably broke but usually resourceful. How do I get him to get me back this money?
P.S. - No physical threats, just what can I say to trick that person into wanting to pay me back?
