Just yesterday I was sitting on a metal stool, eating my lunch at a counter. Everything was fine, and then I got a sharp pain in my left leg that felt like a bug bite. That was manageable, but the pain caused my leg to jerk to the side, thereby whacking it on the stool leg and creating way more pain than the original sensation.
I swore like a sailor (because profanity is one of my guilty pleasures), rubbing my leg until the pain lessened adequately, and continued eating my lunch. Then, as I was finishing up, I took a swig of my seltzer and some of it went down the wrong tube, resulting in that kind of coughing that is more reminiscent of eye-watering and gagging noises than anything else.
Then the burst of rage came.
