Excuse Me, You're Standing on my Last Nerve.

You know how there are certain people in your life who, no matter what they do, are constantly getting on your nerves. No matter how much you try to be nice, or to let them know (subtley, of course) that they are bothering you, they just don't get the hint. And, just when you think that your brain will implode from the effort of being civil, it does.
One such person exists in the community I live in. She thinks we are great friends, and I am trying to be civil, but my head hurts every time I try.
All I have to say is...ARG!
