To the dude at WaWa that tried to make me smile

I do actually appreciate a smile or friendly banter from a stranger most of the time. Except for today, when my mind is so garbled and all over the place I have to concentrate on the task at hand so I'm not really not seeking additional interaction from anyone's peanut gallery. 

I am actually a happy person, though the events and drama of the last four months have made it challenging.  I have my good days and my bad days.  Moments of light and lots of moments of darkness.  So, dude, you have no idea.  I hadn't bothered to tell you about my terminal illness and how it affects my attention span, concentration, and it forces me to conserve energy so I can do important tasks, like work,  because frankly, it is none of your damn business, and I don't like playing the sympathy card, regardless of the reasons.

I don't appreciate being stalked at WaWa from register to gas pump by someone wanting to interact and being chased down the road for two miles, even to tell me in my rush of trying to evade this stranger, that I forgot to put my gas cap back on. I waited till I was no longer being followed by this moron to pull over and reinstall my gas cap, as I didn't want to risk additional drama.

When I ignored you, you should have taken the hint.  When I told you that you needed to back off and how you were being totally disrespectful, you started to swear at me.  You needed to be more perceptive of people's needs and frame of mind.

Sorry dude, you crossed the line, but someday, this will make a funny story about:  how good intentions can backfire AND how to read people -- particularly strangers -- in order not to offend them.
