One question:

Why do boys' socks have sand in them... ALL THE TIME?!?

My brother left a pair of socks here well over a year ago. I wore them... they were full of sand. I washed them - wore them again - full of sand. Washed the socks again - wore them - full of sand. Definite pattern, and endless supply of sand.

Now, what is the phenomena that is happening here? The socks are washed with my other socks and yet, somehow, that one pair of socks (formerly belonging to a boy) always ALWAYS dirties my toes with yicky old sand.

Weird.
