Bumped into the former girlfriend of a friend of mine in LAX once, as we were both flying back to the UK. They had broken up two years previously, and she had been last seen heading for Sydney, Australia. She was on her way home to do a masters in the same town I was finishing up my BA. We ended up having a relationship for a couple of months.

Funny thing was, I wasn't supposed to be in LA at all. I volunteered to be bumped from a different long haul that originated in SF, and my replacement connected in LAX.
