To the Virgins, to Make Much of Time (Gather ye rosebuds)
How we cite our quotes:
For having lost but once your prime,
You may for ever tarry. (15-16)
While we might normally equate losing one's "prime" with getting old, the speaker here connects it with a sort of death. The ominous tone of "you may forever tarry" suggests some kind of eternal solitude, a sort of living death that awaits the single.
