Ever get a gift that was so perfect for you that you actually already had the gifted item? Or maybe you received a gift that was so awful that you wondered if the giver knew you at all. (Sure, it’s the thought that counts, but what were they thinking?!) These are the times when gift receipts and generous store return policies come in handy. But if exchanges aren’t allowed, we may find ourselves contemplating “regifting” (i.e., giving the unwanted gift to someone else), especially with National Regifting Day approaching on the Thursday before Christmas. We may feel ashamed or opportunistic, however, about presenting someone with a gift we didn’t want ourselves in light of the distinct social taboo against the practice of regifting. (Remember Elaine’s indignant “He recycled this gift! He’s a regifter!” on Seinfeld?). Is this worry justified?
