This demeanor of his is interesting, because in most other areas he's more timid and simple. But show him something risky and potentially dangerous or challenging recreation, and he's right there to do it. Like my sister says, most young kids have a dangerous side to them, but once they get hurt they usually wise up and grow out of it. Not my kid.
For example, his complaint about the high dive at the community swimming pool is that it's not high enough. I guess he'd prefer one that's twelve feet tall in instead of the 8 or 10 foot one that is there. And this six year old is insisting that he wants to try water skiing this summer on Uncle Matt's boat. We'll see about that one.
In the mean time, maybe I should get him some skydiving lessons.
