Higher State of mind

I don't understand how people can be so stupid.

I know that as an aspiring psychologist I should have the same amount of respect for people as I do everyone else, but I can't I just can't. I have tried, but every time I think , "OK, people aren't THAT bad" someone comes out with a forehead slapping, mouth dropping, drooling out of the side of your mouth response. Like the woman who asked me at work today- "are you open?" my reply: "...yeeeessss..."

We were standing at the front door. INSIDE the store...

Then there was the woman who wanted an additional $100 off a tv that was being sold for half its original price because it had been a floor model so there was no box, no remote, and no way of getting a service plan. I said "no ma'am because they are already marked down because of the condition you would be buying it in." 
Her reply: "but there's no box or remote." 
"Right, that's why it's marked down."
"but there's no remote, I should get another hundred dollars off."

Honey, if you have a $100 remote at home- feel free to hook it up to this tv.

Why do people have to be so argumentative about stupid stuff? Sometimes I think I should just walk around with a stack of papers that say "her's your sign" and just pass them out instead of face palming myself because of stupidity. It would save me a lot of aggravation. Not to mention a permanent red print on my forehead. 

Maybe we should stop worrying about global warming and start pointing our efforts to trying to cure stupid...

maybe that will be my goal as a psychologist.
