Let’s not unman each other — part at once; All farewells should be sudden, when forever, Else they make an eternity of moments, And clog the last sad sands of life with tears.

Byron urges a clean, immediate separation rather than a prolonged leave-taking. “Let’s not unman each other” frames extended goodbyes as emotionally weakening, stripping both parties of composure and resolve. The lines argue that when a parting is final (“when forever”), lingering only magnifies pain: each additional minute becomes a miniature “eternity,” and the remaining “sands of life” (an hourglass image for mortality and limited time) are weighed down by tears. The passage captures a Byronic tension between intense feeling and a cultivated stoicism—acknowledging grief while insisting that dignity and self-command are best preserved by abruptness.
