How do they get so dirty so fast?

Alright, well, we didn't buy any Halloween candy today, much to Sydney's chagrin, but my house is all decorated for the holiday. So, by that measure, it was a productive day.

Do you think that maybe if I left my reading glasses next to Brian's sink every night, in the morning he would wash them after he washes his own glasses? I'm inclined to think no, but I may try anyway. I foresee laughter at my perceived laziness, but really, it's all about letting the guy with the real experience take on a task that I don't like doing. Besides, he does it, like, every day, where I really only wash my glasses when they're too gross to see through.
