Return on Investment

Dear Diary,

Last year I replaced all the windows in my house with those expensive,
double-pane, energy-efficient kind. But this week I got a call from the
contractor who installed them, complaining that his work had been
completed a whole year ago, and I had yet to pay for them.

Boy oh boy, did we go around!! Just because I'm blonde doesn't mean that
I am automatically stupid. I proceeded to tell him just what his fast
talking sales guy had told me last year: namely, 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
have not heard back.

Guess I won that stupid argument!
