In the pre-internet days, I had a watch that I adored.  Swatch watch with a transparent face so you could see the movements.  A kid asked me if he could borrow my watch one day, to see if he liked it.  I said sure.  After class, he disappeared.  He told me he lost the watch.  A few days later, he shows up to school with my watch and tells me his mom bought it for him.  I was a big, nice kid who was always afraid to hurt someone.  That was the moment when I was pushed past my limit.<p>I waited until after school and then beat the crap out of him until he admitted what he had done and got my watch back.  It was my fault for being that naive.  It was his fault for flaunting my naiveté in my face.
