Lock up all your trees!

Another conversation with Luke:

Luke:"Mom,where does wood come from?"
Me: "Trees."
Luke: "How do you break trees?"
Me: "Usually you need a chainsaw or an ax to chop them down. It is hard work."
Luke: "Do we have a saw in our garage?"

I then clued into what he might be wanting to do.

Me: "What tree are you planning on cutting down? You need to work in a forest in order to cut down trees so you know which tree is the right one."
Luke: "Darn it."
