@roger,
I was chatting online with Andy years ago....remember when we all chatted?
Anyway, for some reason I thought I was chatting with Gautam, not Andy.
I began gently teasing him about his sex life and whatever the hell man he had the hots for at the time.
Gautam was oddly silent.
Then he said he thought I was mistaken, he wasn't gay.
Thinking Gautam was teasing me I reiterated my many reasons for disbelieving him.
Then I finally realised it was Andy I was speaking to!
