One man's folly is another man's wife.

Rowland’s epigram plays on the proverb-like structure “one man’s X is another man’s Y” to make a sardonic point about romantic choice and social judgment. What one observer dismisses as foolishness—an imprudent attachment, a risky match, an infatuation—may be precisely what another person embraces as a life partner. The line also hints at the subjectivity of taste and the limits of outsiders’ evaluations in matters of love and marriage. Typical of Rowland’s early-20th-century wit about courtship, it compresses a skeptical view of “good sense” in romance into a single, memorable reversal.
