I know I'm not the only one who this happens to. I hope. You look at some written copy really fast and you think it says something other than what it actually says.
For instance, once a few years back, I was parking my car on Beverly Dr. in Beverly Hills right in front of The Gap. (depressing, isn't it, Beverly Hills having a Gap)
While in the midst of fishing for meter change, grabing my bag, getting out of the car, feeding the meter and heading off, I glanced at the store and there in the front window was a lineup of mannequins in jean and two or three different colors of t-shirts piled on each. The huge sign announced "Lawyers of Color". I kinda thought it was odd, but remembered it was February, and everyone knows that February is Black History Month, and this being B.H. I just figured The Gap was doing their Legal-Profession-Black-History-Month-Tribute. About an hour later I got back to the car and noticed the sign actually said "Layers of Color" referring to the t-shirts.
My dear friend Charlie and I play a game with each other called, "What It Said-What I Saw", the game can also be played as "What I Saw-What It Said" if the payoff is better that way.
So this morning, while paying my daily visit to Chateau Thombeau and looked at a sentance,
WHAT IT SAID: Farewell, 2009. You didn't kill us---you made us stronger!
WHAT I SAW: Farewell, 2009. You didn't kill us---you made us sausage!
