A story from a friend:
Last year I replaced all the windows in my house with those expensive,double-pane, energy-efficient kind.
Today, I got a call from the contractor who installed them. He complained that the work had been completed a 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 told me lastyear... that these windows would pay for themselves in a year ... Helllooooo? It's been a year, so they're paid for, I told him..
There was only silence at the other end of the line, so I finally hung up. He never called back. I bet he felt like an idiot.
