Can you become gay by hanging around with gay people?

There seems to be an idea, held up by a few people, that you can become gay by association. I've heard this said a lot, in relation to gay men adopting children, that almost certainly these children will become gay. Personally, I haven't seen any evidence to support this at all, and I think I can quite categorically say that you don't become gay by hanging around with gay people.
