First though, I LOVE my new co-teacher. We often interrupt each other to say the same thing. We are literally of the same mind and it makes every day just so much fun. Also, she makes me laugh.
Ok, now for the funny babies --
Me: What is this?
Student: A comma.
Me: Right. And what do we use it for?
Student: We use commas because they are commas and we really should use them because we like them and they are commas.
Perfection.
