From “The Anniversary”

All Kings, and all their favorites,

            All glory of honors, beauties, wits,

The sun itself, which makes times, as they pass,

Is elder by a year now than it was

When thou and I first one another saw:

All other things to their destruction draw,

            Only our love hath no decay;

This no tomorrow hath, nor yesterday,

Running it never runs from us away,

But truly keeps its first, last, everlasting day.

--John Donne
