stupid is about having sense or not.
it is the general concensus that not wearing a sealtbelt is a stupid thing to do, hence your actions, despite having been in more than one accident, is stupid.
saying someone/something is stupid isn't offensive when it's a statement of fact.
it's not a personal attack, it is stating an observation.
calling someone "dumbass", however, is offensive.
anyway.
this is a kid who's just admiteded to continual DUI.
kinda says it all.
not wearing a seatbelt,
failing to see that a particular road/turn/juntion is recommended to be driven at 15mph,
(do i need a sign to tell me a particular bend should be taken slowly?)
drunk driving.
shall we play that game again?
