I managed to leave my backpack on the bus yesterday, and nearly nothing of value was lost.
The backpack itself was over 10 years old and was starting to have zipperfails. I had a set of gym clothes in there,* a pair of headphones, and a pair of sport goggles.**
Maybe it'll turn up in the lost and found, but I'm okay if it doesn't.
