The wettest rain I've ever been caught in was in September 2010. I'd been on an 'Open Doors' visit to Bristol University, and, as I left, it started drizzling. It's about a fifteen-minute walk from the university to our house. After five minutes the rain was sheeting down and after ten minutes I was wetter than I've ever been before or since. I didn't have an umbrella or jacket, and got completely soaked. When I got home I stripped off in the lobby, gathered up my clothes, dumped them in the bath and had a shower to warm myself up. A thunderstorm in Rome in 2014 was a close second, but we were able to take cover in a cafe for the worst part of it.
