Last year I replaced all the windows in my house with those expensive, double-pane, energy-efficient kind.
Today, I got a call from Home Depot who installed them.  The caller complained that the work had been completed a year ago and I still hadn't paid for them.
Helloooo,........... just because I'm a Senior Citizen doesn't mean that I am automatically mentally challenged.
So, I told him just what his fast-talking sales guy told me last year--that these windows would pay for themselves in a year---
Hellooooo? 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.
