Gift exchange is odd, even paradoxical. Giving requires calculation; one must consider the recipient’s need and one’s capacities. And, after the gift is given, expectation sets in. Was it well received? Will it be reciprocated? As many have noted, the gift, though ostensibly selfless, is very much an interested activity. All the calculations leading up to and following a gift exchange reveal the rules that govern a society, even the tacit ones. The gift is an object and a process. The gift moves, and it also—as a keepsake or memorial—stays put. The gift is personal, social, and cosmic.
