heh,
I'm the kind of guy who suspects everyone and anything.
Say for example I am driving, I will suddenly start thinking : But what if some dude on the other lane thinks it's fun to ram my car?
Since I work at the airport, I also make up stuff like : Hey what a nice forgotten bag here ( which I will grab to return to the lost and found ) but what if it was purposedly left here to make the place blow up?
Life is the worst disease of all since no one can espace death.
