sand
snips and snails and puppy dog tails. ha! don't you believe it. little boys are made of sand. it leaks out of their pores and ends up in my bed. they sweat it into their pockets, their underwear, and farther south where it ultimately accumulates in their shoes. don't believe me? grab a kid. rip off his shoes and turn them upside down. (the shoes, not the boy.) just see if sand doesn't pour out.
