My oldest son is about 7½ years old, and he finally lost that first tooth. It has been loose for a long time, and it finally popped off (with a little help from dad).
He was so excited. He had just told me, right before it happened, "Daddy, I really want to lose that tooth because all of my friends have already lost at least one, and I am 7½! So I should have already lost one! And I haven't, so I hope this one comes out..."
Next thing you know, in a moment of bravery, I gave it a little push and *pop* out it came.
He said, "wow." I said, "it's about time."
