It's a little known fact...

A little conversation from the dinner table last night:

Jadyn: We need to drink lots of milk or we won't have the little white things.

Julie (her curiosity peaked): What little white things?

Jadyn: The little white things on our fingernails. Remember, you told me.

Julie (perplexed and trying to jog her memory): What do you mean?

Jadyn: If we don't drink lots of milk, our fingernails won't have the little white circles at the top!

Julie: How does the milk make our fingernails white?

Jadyn: When you drink milk, it goes into your fingernails and turns the top white. Those are the little white things.

Julie (laughing): You're right. Drinking lots of milk does make our fingernails strong, but I don't think the milk makes the tops white.
