In the marriage ceremony, that moment when falling in love is replaced by the arduous drama of staying in love, the words "for richer, for poorer, in sickness and in health,' til death us do part" set love in the temporal context in which it achieves its meaning. As time begins to elapse, one begins to love the other because they have shared the same experience, the same moments of duration. Selves may not intertwine but lives do, and shared memory becomes as much of a bond as the bond of the flesh. One might say shared memory is not love itself but a consequence of being in love; but in what people commonly say about long-lasting love, it is the attitudes toward time implied in such words such as constancy and fidelity that recur.
