Recently, I hurt myself in such a stupid way: I was going in for a poke to my friend's belly really hard and really fast, but I forgot about his stomach musclularness and it bent my finger back past a 90 degree angle. My finger bruised at a joint and swelled up for a few days.
Raisin's post about a little brat throwing a tantrum and harming him reminds me of a few years ago when I used to watch my neighbors' kids for them. This little girl was so sweet until she was angered by something. We were playing in her sandbox and something made her angery... She stood up and kicked sand into my eyes. I couldn't see and I was screaming and crying. Luckily, my grandmother was next door and she came to help me get to a sink and wash it out.
My most torturous pain that I can recall was having my braces removed. My teeth are so sensitive, and they use a little spinning, grindy thing to get the cement off. They also used another evil grindy thing to smooth out the edges of the bottom my teeth. But hey, at least my teeth look great... I guess.
