Today I stabbed a kid (with a pencil). Luckily it didn't pierce the skin---jeans are really thick!
It was an accident, of course. You have us tall, gangly twenty-somethings, amidst a classroom of tiny people. It's hard not to feel like Gulliver in Gulliver's Travels. A single misstep on our part crushes their whole foot. A carelessly placed knee catches them right in the stomach. And they just sneak up on you.
Even though the boy was adamant that he was okay, I reported the incident to his teacher. It's always better to be on the safe side where injuries and liability is concerned. Here's hoping for a speedy recovery (and no new injuries)!
