Give me your opinion

I've decided I'm superstitious.... last Friday (the 13th, and the second one this year at that) there was an incident at my school- somebody was accidentally stabbed in the arm with a pencil on the bus, right before the buses left to take people home. (How the heck do you get accidentally stabbed with a pencil!?) Anyway, several of the buses were held up until long after they should have left (not mine, thank goodness) and an ambulance had to be called in, because the pencil went so deep that it hit the poor kid's artery! How, after an event like this, can you not be superstitious? Give me your opinions and share some experiences!
