Installed additonal shelf to make wife happy!

I bought a refrigerator from my daughter that was less than 2 years to replace our refrigerator that was 12 years old. Our old refrigerator was in good working order. The reason for the purchase was more to help my daugther financially than the replacement of our refrigerator. My wife thought that we had helped our daughter enough financially and was a bit critical of the purchase. I asked her what she did like about the new refrigerator and she told me that it did not have enough shelves. I told her that I could order another off the internet. Sixty seconds later I had one ordered. Four days later it showed up at our front door. My wife installed it before I return home.
