It was a predictable scenario really. A guy wouldn't take no for an answer and my bi sexual female friend said "Why don't you pretend you're a lesbian and I'm your girlfriend" sort of thing. We were in a nightclub. So I told him that and he said "are you really?" He seemed confused. But anyway it worked. Now I realise that if he had properly believed it then he might have been keener than ever. And also I realise that my friend actually hoped that too. So that was a narrow escape
