You can't make this stuff up.

Title and email courtesy of my sister (S is my niece, who will be 3 in October):

S discovered something that she thinks is totally hilarious… When we were driving back from AC I turned around and was telling her something and must have raised my eyebrows. All of a sudden her little face lights up and she says, “Mommy! What are those lines on your forehead?!?” (Picture her tone of voice as totally awestruck). “Can I touch it??”. She must have made me raise my eyebrows 10 times so she could see the cool lines. She wanted to know why she doesn’t have any. Hard to explain to a two year old that mommy is OLD and those lines are not that funny to me. Last night she remembered about it and wanted to see the “Rainbow on Mommy’s head”

I must say, I do prefer for the lines on my forehead to be called my "rainbow" rather than just wrinkles!
