Earlier I was playing around with my friend, mind you he had a mechanical pencil in his hand, anyways, I pushed him into a vending machine and he came out of nowhere and stabbed me with it. It hurt for about 2 seconds, then I looked at it. It looked like a little peice of led. So, I took it out, and my a blood started dripping out of the stabbed area. I looked at the peice of lead, and it was a loving inch long. It was stinging alot, but I didn't tell anyone. So, what should I do? Just leave it?
