“Unloved, that beech will gather brown,
This maple burn itself away;
Unloved, the sun-flower, shining fair,
Ray round with flames her disk of seed,
And many a rose-carnation feed
With summer spice the humming air;”
—Alfred Tennyson (1809–1892)
“What lips my lips have kissed, and where, and why,
I have forgotten, and what arms have lain
Under my head till morning; out the rain
Is full of ghosts tonight,”
—Edna St. Vincent Millay (1892–1950)
