I used to hate swimming at school so much that I would always sneak downstairs in the middle of the night and take my swimming costume out of my gym bag and hide it in the house somewhere. Then I'd never have to go swimming at school. This went on for months and I never got caught and my Mum turned into a nervous wreck because the thought she was losing her memory... and then one day she caught me and got super angry. That was kind of bad.
