I WON THIS ARGUMENT!

Last year I replaced all the windows in my house with the expensive double-pane energy efficient kind, and today, I got a call from the contractor who installed them. He was complaining  that the work had been completed a whole year ago and I still hadn't paid for them. Hellloooo,    just because I'm blonde doesn't mean that I am automatically  stupid.    So, I told him just what his fast talking sales guy had told me last year, that in ONE YEAR these windows would pay for themselves!  Helllooooo? It's been a year! There was only silence at the other end of the line, so I finally just  hung up.    He never called back.  Guess I won that stupid argument.  I bet he felt like an idiot.
