Well one of the really bad ones which sort of put me off girls (for about 3 months) was this story:
Ok, it was some time last may/june and there was this girl that I really fancied for the last two years. So i'ld finnally plucked up the courage to ask her out, but in a rather perculiar sort of way. You see my friends friend had her number so i got my friend to ask them for it. I got the phone number and then after deciding that I would ask her out I sent her a text message. I didn't get a reply and the next day at school she asked me if i had sent her a text and me as I'm very shy and i was nervous said no. When I got home I was kicking myself, why hadn't I said yes i was an idiot. So I sent her another text saying that I had infact texted her. She then called me up and asked me if it was me who had sent her a text, this time I said yes. Now the day after when I went to school this guy who i didn't know at all came up to me and said that he was going out with her not only that the whole of my year knew. But it doesn't end there the next day was saterday and some of my friends said that they weren't going out any more. Now I really wanted to see spiderman that weekend so i texted her and said i was going and told her the time and said that it wouldn't be an actual date. So there I was the next day sat in the cinema the next day staring at the door. And to my suprise there she was, I was so happy but then through the door came her boyfriend, her friend (who i had asked out 4 years before), her boyfriend who hated my guts, and some other guy who i didn't really know. I've only ever in 16 yrs asked 3 people out (and you can see why) and each and every one of them has said no. (The last one was only two months ago and she was nice and kind about it and we're now friends. But those 4 days (especially the last one) were probably some of the worst days of my life.
