It never ceases to amaze me how quickly some people can go from, "civil" to, "stark raving mad." Looking back, its usually some innocuous thing which rational people wouldn't even pick up on. I have noticed that in a great turn of the wheel of irony, my being civil is enough to set people off! A very odd thing indeed.
For all my faults, I'm ever thankful I'm not one of those unbalanced people.
