Some thing that looked like a cake that my ex mother-in-law made ! She was the worlds worst cook. I said Thank you and chucked it in the garbage when she left. Even my dogs just sniffed it and wouldn't touch it !
A house isn't a home without its occupants, so I am sure you house would want you to partake in the celebratory ham. Afterall you and your family are what made it more than just a house. You made it a home!
