DS lost his first tooth a month ago. He refused to put his tooth under his pillow because he didn't want some strange lady with wings in his bedroom. I tried to reason with him about how he doesn't mind Santa or the Easter Bunny, and he said, "Mom, they've been coming since I was born. I've never met the Tooth Fairy in my life!" So we compromised by leaving the tooth on the kitchen counter with a note instructing her to please not come in his room.
Second tooth was lost day before yesterday. He agreed that she could come in his room this time. Except, she, um, sort of forgot. He came down to breakfast pretty crushed yesterday, and I told him she must be on a holiday schedule because it's Thanksgiving. He brightened up and said "Like the garbage men!" Yep, son, exactly like that. So last night she left a dollar coin and a note explaining that she'd been MIA because she was invited to take part in the Macy's Parade, and to please accept her apologies.
I think he bought it.
