" When I was a kid I used to drink from the tap all the time. I'd run back into the flat all hot and sweaty from playing and didn't even bother putting it in a glass, just turned the tap on and stuck my mouth underneath it. If my mom caught me doing it she used to scold me, but my dad just said that I had to be careful. 'What if a fish jumped out?' he used to say. 'You'd swallow it before you knew it was there.' Dad was always saying stuff like that and it wasn't until I was seventeen that I realised it was because he was stoned all the time. "
