Last year I replaced several windows in my house. They were the expensive, double-insulated, energy efficient windows. This week I got a call from the contractor complaining that the work has been done for a year and I had failed to pay for them. Boy, oh boy, did we go round and round. I told him no one pulls a fast one on this ole' lady. Although I am a senior citizen and used to be a blonde, that doesn't mean that I am automatically stupid! I proceeded to tell him just what his salesman told me last year, "That in one year they would pay for themselves."
