Student 1: Woah! Look at that pond!
Student 2: I know! It’s green! Green is my favorite!
Student 1: Are there sharks in there?
Me: No, buddy. Don’t worry there’s no sharks in there.
Student 1: Are you sure?
Me: Yeah, it’s a pond. Sharks live in the ocean.
Student 2: Well there could be. If there was a stream that went into the pond and that went into a river and that went into the ocean, then there could be sharks here.
Me: Well, you’re not wrong.
