re: Lesson learned
I learned that lesson when I left my watch (16th birthday present- Pulsar) in my bag, on the bus, while I ran a Cross Country race. I didn’t want the watch to get messed up.
When I got home and went through my bag, it was gone. I rode my bike up to the school and searched the bus to no avail.
I suspected this one kid, but I never found out for sure.
My son learned the lesson last year when one of his classmates took his Pokeman cards out of his backpack.
