Where Did THIS Kid Come From?

I picked up Monkey's friend for a playdate about 45 minutes ago. The second he got in the car he said the following:
Hey Molly! How's your summer going? You know what my favorite baseball team is? It's not the Phillies. It's the sharks. I went to their game and there was a shark there. But don't worry. He wasn't real or anything. Just a man dressed up as one. And I wasn't even scared. I'm actually really brave. You know why? Because I'm five. Monkey's only four- right Monkey? But don't worry we can still be friends.

After we got home we went in the house and Mr. Z (the friend) JUMPED into my arms, because the 4 month old golden retriever was TERRIFYING to him.
