The context of the following conversation is After Casey's tooth fell out, Kendall put money under Casey's pillow while Casey was sleeping.:
Casey says I had a visit from the Tooth Fairy last night..
The friend responds Cool! How much did you get?.
Casey responds A dollar. But I'm starting to doubt that it really was the Tooth Fairy..
The friend responds You are? Why? Who else would give you a dollar for a tooth?.
Casey responds I was half-awake in the middle of the night and I thought I saw Kendall come in..
The friend responds I don't know, I believe in the Tooth Fairy. Maybe you just had a dream..
