Thankfully my days of first dates are over!
The only first date disaster I had was when I was about 17/18... I'd had my eye on this guy for ages. He went to a different school to me, was outrageously good looking, played rugby etc etc. He eventually asked me out and we arranged to go to my local pub as I knew my buddies would be there and I promised them I'd go and show him off.. when we got there my friends were all exchanging humorous looks and trying not to laugh. Puzzled, I dragged one of them off to the loo to ask what was so funny and it turns out the whole town knew him as the John Menzies wanker; he worked there at weekends and had somehow been caught relieving himself with a sock in the toilets!
It didn't totally put me off, but he spent the rest of the night talking of nothing but himself, then our next fate he invited me to his house and when I got there he had the Trivial Pursuit set up.... I had to give him the "its not you, its me" talk
Then he phoned my Grandma twice asking what was wrong with me and asking her to talk me into going out with him again. Jesus!
