Sometimes I wonder if men and women really suit each other. Perhaps they should live next door and just visit now and then.

The remark wryly questions the assumption that romantic partnership requires constant proximity. By proposing “next door” living and occasional visits, Hepburn (or the speaker to whom the line is attributed) highlights how intimacy can be strained by everyday cohabitation—habits, expectations, and gendered roles that turn affection into friction. The humor carries a serious point: autonomy and personal space may be essential to sustaining desire and mutual respect. Read in light of Hepburn’s public image as fiercely independent, the line is often taken as a critique of conventional domestic arrangements and a defense of relationships built on choice rather than obligation.
