Lost and found on the bus

Today, I went to Toronto General Hospital with my student performers. As usual we went to catch a bus to go downtown. One of the students picked up a paper and started to do the crossword in a paper that she picked up. She was happily doing the crossword and then we got off the bus and boarded the Subway. It was then that she realized that she had left her music on the bus. Luckily it is photocopied, I carry the originals. She did not have her piano music unfortunately but that was not something we could anything about. Luckily, we had plenty of music and the performances in the cardiac ward and psychiatrict wards went well.
Then after a snack, it was time to head home. We retraced our route taking the subway and deciding to go back on the same bus route. We got on the bus and noticed the same messy seat, one of the musicians looked in the corner and found the piano music folded. The folder and clarinet music were missing but the piano music was there. What were the odds of getting on the same bus? This is a very busy bus route and we just took the first bus.
Too bad that the folder and clarinet music were missing but I will copy them tomorrow.
Very strange!
