Song, by TS Eliot

If space and time, as sages say,
    Are things which cannot be,
The fly that lives a single day
    Has lived as long as we.
But let us live while yet we may,
    While love and life are free,
For time is time, and runs away,
    Though sages disagree.

The flowers I sent thee when the dew
    Was trembling on the vine,
Were withered ere the wild bee flew
    To suck the eglantine.
But let us haste to pluck anew
    Nor mourn to see them pine,
And though the flowers of love be few
    Yet let them be divine.
