We do a family gift exchange--my mother's siblings, their spouses, children, and grandchildren. There are about 20 of us, and we're pretty close and see each other regularly.
I don't think I've ever received a thank-you card, thank-you phone call, or even an acknowledgement of the gift's receipt. The past three years, I've shipped the presents to California, and the only way I know they receive it is when the UPS shipping confirmation e-mail comes into my inbox.
Why do I still do this blasted exchange?
