When traveling with someone, take large does of patience and tolerance with your morning coffee.

Attributed to the actress Helen Hayes, the line uses a domestic, humorous image—morning coffee—to point to a common stress point in shared travel: fatigue, disrupted routines, and close quarters. The “large dose” metaphor suggests that patience and tolerance are not occasional virtues but daily necessities, especially at the start of the day when irritability can be highest. Implicitly, it reframes successful travel companionship as a practice of emotional self-management and generosity rather than perfect planning. The quip also hints that minor frictions are normal; what matters is meeting them with deliberate forbearance so the trip strengthens rather than strains relationships.
