Last year I replaced all the windows in my house with those expensive double-pane energy-efficient kind.
Yesterday, I got a call from the contractor who installed them. He was complaining that the windows had been installed a whole year ago and I had never paid for them yet.
Helllooo? Now just because I'm blonde doesn't mean that I am automatically stupid. So I told him just exactly what his fast-talking sales guy had told ME last year... namely, that in just ONE YEAR these windows would pay for themselves! Helllooooo"? (I told him). "It's been a year"!
There was only silence at the other end of the line, so I finally just hung up.... He hasn't called back, probably too embarrassed about forgetting the guarantee they made me. Bet he won't underestimate a blonde anymore.
