I work with a girl who, when I told her I windsurfed, she said "I used to go out with a guy from Torquay that windsurfed...him & one of his mates were pretty good, I think his mate was one of the best in the area - Jason Polakow...we used to go to a few parties at his house, he was a bit mad...have you heard of him?...I doubt he still windsurfs though, that was a few years ago!"
I've never mentioned windsurfing to her again after that!
