Yep,I did it to my gym teacher by accident it was really funny. Cuz I was using my hands to talk (Like I always do) and I hit her. I laughed then she gave me a lecture. Then I hit a guy named Collin on purpose.
Oh, there was this one time where I was at my softball game, and the girl who was hitting before me got hurt, and they had to call out a pinch runner. When I was up, I thought the pinch runner was already out there, so I started taking practice swings (just my luck: metal bat). So, of course, the pinch runner, who happens to be the widely-renowned best female athlete in the area, isn't out there yet and walks out of the duggout (sorry if I spelled that wrong) right when I'm swinging. And, of course, it whacks her in the arm.
She said it was okay, but, after the game, I saw her rubbing her arm and asking her parents for an ice pack.
