One early morning at the beach, Caroline woke me up with this
Caroline: Daddy? Did you know? Some trees are medium.
Caroline: I said 'Daddy, did you know some trees are medium?'
Me: You mean, like, some tress are tall...
Caroline: Yeah, like this big [holds hands way apart] and some trees are like this [holds fingers close together] and some trees are medium.
Me: Can I go back to sleep now?
Caroline, Joey and I are walking down the street, and Joey is riding on my head.
Caroline: The boys are together!
Caroline: And together, you're medium!
Me: How do you mean?
Caroline: Joey is small, you are big, and together you are medium.
Me: No it doesn't work like that when you put heights together. If you put something small on something tall, you get something that's extra tall. You don't average them.
Caroline [petulant]: No! You and Joey are medium.
Me: OK, fine, we're medium.
