I was sitting at the coffee shop enjoying a coffee and reading the paper when suddently an earth-shattering explosion ripped through the building. Windows rattled, coffee spilled. Remembering my early training on how to protect oneself against nuclear attack, I sought cover under the table at which I was sitting. Without much expectation of survival, I waited for the next and likely last explosion. But this time I was prepared. To my utmost relief, the sound had emanated from the man at the next table. His cough/sneeze began deep within his chest, only a heartbeat away, as tremendous pressure built within his torso. And then... the violent explosion that had so startled me just seconds earlier.

Why is it that so many people seem to be unable to stifle these explosive infringements to my quiet enjoyment?
