The House that Parker Built

Should I be worried that my son likes to dismember and destroy things? Just last week he took apart our old fan (after it blew up in his bedroom) and scattered the parts all over the garage. He did put it back together after we explained that the garage was actually for us to park the car in, not his personal workshop.
Then a few days later he wanted to know if he and his friend could take Yancey's hatchet and shovel into the woods behind our house. I know, this sounds like the beginning of a scary movie. They worked up a sweat hacking down as many small trees as they could and leaning them together against another tree to make a club house. I'm sure that if these same boys had to chop wood as a chore, it wouldn't be nearly so much fun. They actually created a pretty cool-looking lean-to structure. I know this, not because I actually walked into the woods myself (a nature girl, I am not), but because Parker took my camera back there and took about 30 pictures of it. I think he gets his affinity for hacking things down from his father, whose first instinct when we bought our house in the woods was to start cutting down trees.
Anyway, positive things about this story...Parker actually asked before he used his dad's tools, he actually put them away when he was finished, and he built something with his own two hands. Perhaps what he loves is not destroying things, but creating things. He just likes to rearrange the parts!
