Tooth Fairy?

Eeck, she's growing up too quick too fast! Last night she asked me if I was the tooth fairy, because a classmate told her he'd heard his parents putting the money under his pillow when he'd lost a tooth recently. PANIC? Naah, I just calmly denited it and told her I did not put on any wings and shrink myself, and that I had no use for her teeth. And, I wasn't lying! Since its not me who puts the money under her pillow (and if you can't guess who I'm not gonna tell you LOL!) I'm just afraid that our Santa days are probably numbered, hope we get at least one more Christmas before she realizes the truth... and I guess I should be happy that she's not smart enough to figure out she could try and milk things longer.
