So, I lent my friend Lares $20 the other day. He was going to a Springsteen concert after work and had forgotten to bring his wallet that day. So, no biggie, I happened to have it on me and we had just gotten paid, etc. So yesterday I ran into him and he was telling me about the concert and there was no mention about the money (he had said at the time that he would pay me back the next day). I didn't mention it either. So now I feel a little awkward about it. Do I bring it up? Do I wait for him to remember? I hate to come across as a cheap-ass or a nag, but I also can't afford to be throwing $20 bills away. Maybe I'll give it until next week (by which time he is sure to have completely forgotten about it). ARGH!
