Tooth fairy

Well, it's official. The youngest son doesn't believe in the tooth fairy who in the past has taken two days to arrive at this house because there are so many other children who have lost teeth.

Lee, who turns 7 in November, lost another tooth tonight - at dinner.
I thought the white speck on the tip of his tongue was a chopped onion.
"Spit it out if you don't like it, Lee," I said.
"It's not an onion, mom. It's my tooth," he said as it landed on the table.
"Well I think the tooth fairy will be visiting our house tonight," I said.
Long pause.
"I don't believe in the tooth fairy," he said.
"What?????? You don't believe in the tooth fairy?????"
"My mom and dad bring me money when I loose a tooth."
"Oh."
"Dad told me that ... but maybe he's lying."
Pause.
"Lee, do you believe in Santa Claus?"
"EVERYONE believes in Santa Claus."
"OK."
