How long a minute is, depends on which side of the bathroom door you're on.

A comic “law” about subjective time: the same objective minute feels radically different depending on your situation. If you’re waiting outside a locked bathroom, urgency and impatience stretch time; if you’re inside with someone waiting, embarrassment or pressure can make the minute feel either fleeting or agonizing. Like other pseudo-scientific aphorisms (e.g., Murphy’s Law), it uses everyday experience to illustrate a psychological truth: perception of duration is shaped by emotion, stakes, and bodily need. The bathroom-door image makes the point vivid and universally relatable, turning a familiar social scenario into a memorable observation about relativity in human experience rather than physics.
