Cowboy

The other day, Isaac and I had the following conversation while on the way home from school: 

Isaac: When I grow up, I'm going to be a cowboy because I will have a gun. I won't shoot it all the time, just some of the time.
Me: Oh yeah? What are you going to shoot with it? 
Isaac: I'm going to shoot dear to eat.
Me: Does that mean you are going to live in the wilderness? 
Isaac: Well, I'm going to live in a shack, is that where they have shacks? 
Me: Why are you going to live in a shack? Why not a house?
Isaac: Umm...mom, because I'm a cowboy and I don't know how to build a house. 

Okay son, you have clearly given this a lot of thought.
