I had all these badges, my Deutscher Jugendschwimmpass, by the time I was ten. Once during lessons I got into a fight with my swim instructor, I was about 5, he was an old man with a beard, he was trying to force me into the pool. I punched him, I pummeled him with my tiny fists. I am pretty sure he hit me back. My mum came along and whisked me away, I did not swim that day.
