    Apparently I'm an asshole for making light of a tool for the blind. It's an ultrasonic object detector that goes on a blind person's guide stick (it vibrates when an object is in their path). But this seems redundant--isn't that what the stick was for in the first place? (cue angry mob of Hellen Kellers who desire nothing more than to administer the worst guide stick beatdown on me since the days of Rodney King)
