Why was it dumb?
Dumb is lying down on the railroad tracks in the way of an oncoming train.
Dumb isn't doing what 99% of the population does, not unless you knew ahead of time that going to a Mogwai concert without earplugs could actually cause real harm to your auditory system.
So, Lisa, did you know ahead of time that you might develop severe intrusive tinnitus that might literally change your life? I bet not!
It was dumb because 2 years beforehand I did a schoolproject where we actually tried to raise awareness about earplugs and hearing loss (T wasn't really emphasized though..). I would ALWAYS wear earplugs to concerts and the like. It just took one time unprotected to one of the loudest bands ever (+ I was tipsy, so I wasn't paying much attention to my earplug policy) to make T happen.
But this is in no way saying that we should avoid concerts and such. Do what you love and do it passionately. Why do we live otherwise. To suffer? I just make sure now I'm always protected, even more then I did before. But I still go clubbing etc. I'm even going to tomorrowland this summer
