Snow plow or truck?

I know, I know, I know. My grandma and Aunt Mady already reminded me that I haven't posted in a l-o-n-g time. They were happy to see Harrison's crazy hair picture but I'm sure they would appreciate more. :)

I've enjoyed the mini blog vacation and haven't put much thought into writing on here until this morning. The van conversation was too good to forget.

Harrison: "Mommy, look! What's that?"
Me: "A snow plow."
Lily: "A snow plow is a truck."
Harrison: "No truck, snow plow!"
Lily: "A snow plow IS a truck!"
Harrison: "NOOOOOO!!!!"
Lily: "YES!!!!!!"
Harrison: "NO!!! SNOW PLOW!!!"
Lily: "A snow plow IS a truck!!"
Harrison: "NOOOOOOO!!!!!!!!!!"
Lily: "YES!!!!!"
Harrison: "NOOOOOOO!!!!!!!!!!"
Lily: "YES!!!!!"
Harrison: "NOOOOOOO!!!!!!!!!!"
Lily: "YES!!!!!"
Harrison: "No, snow plow."
Lily: "A snow plow is a truck, Harrison."
Harrison: "Huh?"
Lily: "A snow plow is a truck."
Harrison: "A snow plow is a truck?"
Lily: "Yes."
Harrison: "Oh."

After my initial answer I stayed out of it. They went back and forth for ~5 minutes but they ended up working it out.
