I was out with someone this afternoon and one of the places we went to was the Arboretum part of Nottingham. While there, we encountered a pro-environment festival that was being held; I had read the other day that it was on but I forgot about it.
Two odd events occurred: The first was that I found a £10 note on the floor. I didn't want to keep it but at the same time, if I reported it as missing, there was too high a chance that someone who never owned it would claim it. As such, I gave it to one of the charities at the festival. I didn't want it so why not give it to charity? At least the money will benefit someone by my giving it away.
The second was that I encountered my old mathematics teacher from Pre-Access! I saw him at a distance as he walked towards us and when he became close to us, I recognised him as my teacher. He was with his other half and did not appear to see me. Not a big deal - I hope he had an enjoyable afternoon, too.
