I have my moments. Normally, I am a pretty forgiving kind of guy. But, there are the days when the blood sugars are low and the sleep quota is less than it should be. My normal placid aura becomes a dangerous, seething cauldron of raw intolerance. Old ladies, who on another day might well be helped across the road run the risk of having the walking sticks kicked from their arthritic grasp. That casually dropped cigarette butt gets dropped back in the window of the offenders car. And, God help the errant dog-walker who does not clear up after their pooch. Yes, I have days when I can be totally hard-assed.
