A funny conversation with Arielle

First funny conversation, when Arielle was just turning 2:

(Context: on the way to daycare)

Me: Arielle, do you see a tree?
Arielle: Yes, I *do* see a tree!

Arielle: Do you see a car?
Me: Yes, I *do* see a car!

Me: Do you see a mailbox?
Arielle: Yes, I *do* see a mailbox!

(By now, I think you can get the idea of this game: develop vocabulary and observation skills)
(Or so I thought)

Arielle: Do you see a fire truck?
(pause, as I slow down and look everywhere for the fire truck. My God, I thought, her observation is really keen if she spotted a truck somewhere! Maybe it was a toy truck? Where could it be?)
Me: No, I don't see it.
Arielle: Me neither
