In Covid, I told a mate that I thought labradors were boring dogs. She hasn't spoken to me since. She didn't have a labrador. She wasn't thinking of getting a labrador. No idea what that was about.
In 1998, a girl at school borrowed my Backstreet Boys pencil case and took too long to return it. I gave her the silent treatment for a few days, but then it was the six-weeks holiday, then it was the new school year, and time just ran on. We haven't talked since despite living just around the corner from each other.
When I was 16, a boy I was seeing bought a really ugly yellow jumper, and wore it on a cinema date. I pretended to go to the loo half-way through the film, left the cinema and then just ignored him calls and visits forever.
