Why should the world be over-wise, In counting all our tears and sighs? Nay, let them only see us, while We wear the mask.
Why it works
The closing "We wear the mask" here is the rentrement in action — pulled verbatim from the poem's opening line and dropped, unrhymed, at the end of the second stanza, functioning as the structural echo that defines the rondeau form. Its brevity and isolation on its own line, surrounded by the A-rhyme couplet above it, show exactly how the rentrement punctuates rather than continues the rhyme scheme.
