It happened when I was in kindergarten. I was sitting next to a friend on the bus and she got into an argument over something with the two boys across the aisle. Being that we were all 5 year olds, this quickly devolved into name calling. I particularly got into it with one of the boys and he threatened to punch me if things kept going. I though he was bluffing and we all continued with the verbal slap fight until the bus arrived at the school. At that point we got off and lined up to enter the building. Everything seemed to be over at that point. It was not. He delivered on his threat.

He was immediately taken to the principal and I was sent to the nurse. The next day all four of us had to apologize.
