Some things that I have pondered lately:
Yesterday, my fortune cookie at Five Happiness read, "If you think you're too small to be effective, you have never been in bed with a mosquito." These words ring so true, for me especially.
Every time I walk into my bathroom, my cat follows me in and jumps into the bathtub, crying. She does this, I think, for no reason at all.
If for some reason you got into a fight with a ten year old kid who has a triple black belt in karate, even if he was able to defend against your intial assault, I'm doubtful that he could do any damage to you after that and you'd just both be like, "Now what?"
