The Blonde Way

Last year I replaced all the windows in my house with the expensive, double-pane energy-efficient kind.
Today, I got a call from the contractor complaining his work had been completed a year ago and I had yet to pay for them.
Boy, oh boy, did we go around and around!
Just because I'm a blonde does not mean I'm automatically stupid.  So, I proceeded to tell him just what his fast-talking sales guy told me last year - namely, that in one year, the windows would pay for themselves.
There was silence on the other end of the line, so I just hung up.  I have not heard anything since.
Guess I won that stupid argument!
