One day a girl of about twenty moved into the flat opposite mine. She was a little chubby and had a shy smile and refined manners. I saw her arrive in the removal van and volunteered to help her with a piano that was being carried clumsily by two guys that turned out to be her brothers. Since I was recently divorced and had nothing better to do, I helped with the removal all afternoon and made friends with the pianist.
