An elderly couple pulled into a full service petrol station and the attendant asked the gentleman driver if he wanted the wind shield and windows wash. "Certainly" he replied.
The elderly man looked at the windows after they were washed and thought. "It's pretty dirty and I'm going to ask him to wash again."
At the moment, the wife reached over and grabbed the eyeglasses from off her husband's face, wiped them clean and put back on his face, resulting her husband eventually saying "The windows look great!"
hmmm... what do you think?
Attitude is your state of mind, or that looking glass through which you see the world. If the glass is dirty, you will interpret everything accordingly.
