Dear Driver of the blue Kia with the politically-charged bumper sticker,
I won't judge you on your political beliefs. I'm a bigger person than that, and I believe that, despite our differences, we can all get along.
I will judge you, however, on your horrendous driving. Assuming that I will "wave you on" when I clearly have the right of way because in your narcissistic world, everyone does what you want, is presumptuous. And wrong.
Don't let it happen again. Next time, I might not be as generous to allow your rudeness.
And I take it back: we can't all get along.
