On the Way to Her BFF's

As I was driving Brianna and her best buddy to his house last week, I overheard them talking in the back:

B: I love your house!  It's like a castle!  Seriously, with all those bricks going up, up, up!
Q: I know, but it's not a castle, it's like a temple.
B: Ya, totally.
Q: Because castles always have that water around them, so that if someone's trying to get in, they just fall right in the water.
B: Ya, castles have the water that goes all around the outside.  So the guys go "la, la, la, AAaaaah!"
Q: Ya, that's what I just said.
B: Ya, and I would 'spect that they have sharks.
Q: Ya, sharks.
B: Or dolphins.
Q: No, not dolphins.  Dolphins don't eat people. Sharks do....  Or killer whales.
B: If I had a castle, I'd have dolphins in my water.
