I just left a mean note on someone's car, what's wrong with me?

[cfield]

So, I took my car to (EEK-GASP-NOOOOO) Wal-Mart (don't yell at me, it's by necessity, not by choice) on my lunch break to get an oil change. I walked across the parking lot to get a yummy burrito for lunch and as I was walking back some lady pulled into a parking spot about 4 down from the very end; farthest from the entrance to Wally World. Her and her daughter (I'm guessing; about 8 or 9) get out and trudge up to the store. No big deal, I figure anyone motivated enough to park as far from the door and walk is okay in my book. Then I look closer at her little Chevy car, and notice that she is parked in two spots, the yellow line going right down the center of her car. So, I'm thinking, I've seen people with BMW's or other such 'fancy' cars take up two spots to avoid having anyone too close to hit the car with their doors. But a Chevy?!? And, it's one thing to park at the end of the lot, with no cars for at least 28 spaces. But to take up 2 spots? That seems like overkill. And for some reason, it bugged me, so I walked over and left a note expressing my concern with her lack of vision to park correctly and how maybe she shouldn't be driving. Nothing rude, but snarky still. Am I a bad person???
