Last year I replaced several windows in my house and they were the expensive double-pane energy efficient kind. But this week I got a call from the contractor complaining that his work has been completed for a whole year and I had yet to pay for them.
Boy oh boy did we go 'round. Just because I'm blonde doesn't mean that I am automatically stupid. So, I proceeded to tell him just what his fast talking sales guy had told me last year. . 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 and I haven't heard back. Guess I must have won that silly argument.
