you weren't a boy.
that really does explain it.
boys blow stuff up/burn stuff down/test-to-destruction/etc... - the urge to do so is hardwired in us.
There is a new xbox game called "Mercenaries: Playground of Destruction" and the advertisements emphasize the players' ability to blow things up, blow more things up, and blow things up some more. Needless to say, my 13-year old HAD to have it.
LOL!
And we still do!
