Back in 2000 or so I'd been single for a while, and had gone to Manchester to visit friends. We went to a club and I was dancing with a girl who was mates with a friend's other half, and I thought I was in, but it didn't turn out that way. The feedback I got afterwards was that the girl I danced with fancied me at first, but I came across as stinking of desperation (to be fair, I was drunk and pretty damn thirsty for skirt at that point). It really put her off, so she wasn't interested. It was a really important lesson; confidence attracts people, neediness doesn't.
