Mom: Do you know where we are?
Dad: Yes.
Mom: Are you sure? I don't see this on the map.
Dad: Yeah I'm sure, it's a short cut.
Mom: How do you know a short cut? We've never been in this state before.
Dad: You know what...how about you let me drive since I've got the steering wheel here in front of me!
Mom: Don't yell at me, I'm just asking if you know where we are!
Dad: And I answered you.
Mom: You have no idea where we are do you.
Dad: Is that a question or is it a statement. Because if it's a question, I have already answered it. If it's a statement, I don't need you to tell me things I already know!
Mom: so we are lost.
Dad: I didn't say that.
Mom: Yes you did. You just said you didn't need me to tell you things you already know! That means you know we are lost.
Dad: That's not what I said.
Mom: YES IT WAS!!
Dad: THAT'S NOT WHAT I MEANT!
Me: DAD!! WATCH OUT FOR THAT TREE!!!!!
If it were my family the man in your dialogue would be saying, "You'd think I drive for a living or something."
My Dad had shortcuts on family road trips.
If we were in a rural area his shortcut would always terminate on a horribly rutted dirt road.
If we were within 50 miles of an urban area, we would end up touring some of the worst ghettos on Earth.
