Many long years ago I received a gift from my mil that I knew was a re-gift. It was not anything that would have been good anyplace in my house so I tucked it away in the basement. About 20 years later, I re-gifted it back to her. Not sure she even remembered it. lolGreat list!!!!!
Maybe we could all add to the list
#4. Write down who gave you a bad gift, so when you re-gift it next year, you dont get embarrassed by giving it back to the same person (not that I would ever re-gift).
