Beware the Ides of Twinness.
Because it's a guarantee. One of your twins will beg you to get braces. You will spend fifteen minutes at the dinner table explaining the many reasons why she does not want braces: they hurt, the many foods that can't be eaten, how gross it is to get food stuck in the braces.
And then? The other twin will be told she needs braces. And you will spend fifteen minutes during the car ride home explaining
mom doesn't always know what she is talking about the many reasons it's not so bad having braces.
