About seven or eight years ago I was waiting for someone to come back from lunch and open a shop when I realised a middle aged man was staring at me from a bus stop just across the road. After a while he worked up the courage to come over and talk to me. He stopped in front, fiddled about a bit and said "I'm bisexual. Are you?" What? Hang on! He was a man, I was a woman, so what kind of weirdo question was that?
I'm still confused, but not as confused as he was.
