She may have forgotten, but I don't see how she could have thought you were giving it to her. If she said she would measure it and call you so the two of you could agree on a price.........I would have inferred from that she intended to pay you. I, too, get real tired of people not doing what they say they are going to do, just in general, about anything. It gets old. Anyway, I hope you get it worked out.
