what??? a funny

So I'm doing a thorough cleaning today, in a few areas. More on that later.

Eric, bless him, keeps looking at the window area, in a perplexed manner, and finally says, "But what's so different?"
"What?"
"You changed something..."
I looked at the window area, "Well, it's all clean...."
"No," he continues, "Oh! You took the blinds down!"
"No, there were never any blinds...."
It dawned on me, dear Friends -- it's because he can see out of it, the window is clean!!!
Probably I should be embarrassed in stead of rolling on the floor laughing.
