waterbed

noun

1. A bed with a tough plastic mattress filled with water.

   “When I ask to sleep over at my friends’ houses, I am told I am not allowed. Boys are not allowed. My friend Caitie’s mother argues about this on the phone with my mother. I realize my mother is not on my side. Later, my mother tells me Caitie’s mother is divorced, has a tattoo, and sleeps on a waterbed, the relevance of which doesn’t seem clear. I think Caitie’s mother is cool.”
