This may sound obvious, but it's a good idea to respond at least sometimes to the requests from people to play such things as "Happy Birthday", Christmas carols, "Auld Lang Syne", and the like. Lots of folks think that if you play guitar (or whatever) you should be able to play almost anything. I know it's illogical, but some people actually assume that. Anyway, being prepared to play a few songs for "occasions" can make you alot of points with hosts and friends, I'm not sure if it really helps to pick up women...

Peace, Mooh.
