That isn't the point, though I'm sure I was unclear. The point is that I can't filter anything I hear. Every tap of keys, every inane conversation, even the noisy breathing noises from the woman in line behind me at the deli this morning. The point is that the way I process noise is ... temperamental, shall we say. It's literally a brain thing - that insidious form of sensory overload that leaves me quivering. To escape noise, I think I'd have to become a monk.
