:roll: Yes, I've had that reaction too often. My sister told me once when I got laid off from my job, "Good, now you have all this time, you can make me a quilt..." Did she not think that perhaps I might be busy looking for another job? She bought the fabric, and with the agreement, that when it was all done, she would at least pay me for the machine quilting in the end ($150). Of course, when I sent it to her, she sent me a thank you card thanking me for the "gift"....I mentioned to her that it was $150.00 that she owed me and referred to our "agreement"... She then said, "Well, I didn't get an invoice." I replied, "I didn't think I had to invoice integrity..." My check came 1 year later.
It was at that point that I made the decision to only make things for personal use in my own home, grandbabies, for sale, or charity.
NO, people don't get it.
I don't think that we are being unreasonable expecting a thank you note.
