If a male friend of mine made a homosexual pass at me I'd avoid him from that second on..
Something like that happened in the past was when I used to chat to a near-neighbour whenever we bumped into each other in the street.
One day we were talking about militant gay activist troublemakers and to my surprise he said "we shouldn't knock homosexuality until we've tried it".
I never replied, I looked at my watch and said "Oh is that the time? Sorry I gotta get to the shops before they close, bye", and off I went.
Needless to say, if I see him in the street nowadays I do a U-turn or dodge down a side street..
