"Someday you're going to leave me," I tell him as I tuck him in and tickle dream angels into his scalp.  "Some day you're going to meet a girl and fall in love and kiss her and get married and have babies."

Liam screws up his face.  "I don't kiss guwls!"

"I'm a girl," I tell him and I lean over to kiss him goodnight.

"No you're not.  You're dust my mom.  And I don't wanna maywee a guwl."

"Why not?"

"I'm dust gonna maywee a mermaid!"
