I was thinking about this on my drive to work today - I've got one friend that has owed me $100 bucks for about three months. I doubt I'll ever get it back at this point, I'll ask him the next time I see him despite the awkwardness of it all. Another dude owes me $10; he'll probably get it back to me, but if not it's only $10 bucks. Anyone else owed money? I hate it when people don't pay you back promptly; it's such a painful process. I've always made it a point to get cash back to someone a.s.a.p. if they spot me something.
