I'm a butterfly!

I've been volunteering in my son's kindergarten class. Li'l Freddy (not his real name, ya think?) thinks it's nice for me to be there and as long as those good feelings are in the air, I'll take them. His classmates never got my name straight, but I love the derivations: Mrs. Freddy, Mrs. Freddy's Mom, Mrs. Mom. One little girl, Macy, was wearing a pretty, bedazzled shirt with a butterfly on the front.

Me: Macy, I really like your shirt.

Macy: I'm a butterfly!

Me: I can see that!

Macy: But you can't see my wings.

Me: No, I can't.

Macy: Do you know why you can't see them?

Me: (getting with the program, lowering voice to a conspiratorial whisper) Because they're invisible?

Macy: (looking at me like I'm the crazy, three headed Mrs. Mom lady)
No! They're just really small!
