I met a wild dolphin when I was on holiday in Devon once. It swam into the bay and lots of people were watching it in the shallows and about fifty yards out ( they were wearing wetsuits) I got in fully clothed except for my shoes and glasses and swam about midway between the two groups. I wasn’t going to miss the opportunity. Soon the dolphin was swimming around me. I noticed he was male (later found out he was called Georges, an adolescent male). Goodness knows what he thought I was! The next day there was a notice put up saying not to swim near him as you can catch diseases when they breathe out droplets of water, luckily I was fine. I remember he was badly scored along his sides. Apparently he was too interested in motor boats. I still think of him and hope he was OK. I did a painting of him but can’t find it.
