Riddle Me This

Let me give you the "need to know" background information, first.

Thing one: Ben is taking a week long mosaics art class in the mornings this week.

Thing two: I'm trying to keep frogs away from the pool.

Ok, here are the two conversations Ben and I had this morning during the same 10 minute car ride.

Conversation #1:

Me: Did you start the mosaic or are you still planning it?
Ben: Uh, I don't remember.
Me: But it was, like, 10 minutes ago.

Silence for about 3 minutes, and then......

Conversation #2:

Me: Hey, do you remember where that big rubber snake is?
Ben: The one I got from the Tulsa zoo the first time we went?
Me: Ben! That was six years ago!!
