Why an unexpected touch can feel intrusive
In Thailand, people who are not close often use their voices rather than a hand on the body to get one another’s attention. A shoulder tap may seem minor to the person giving it, but it crosses a boundary the other person did not expect—especially if they are absorbed in a task or cannot see who is behind them.
The surprise is part of the effect. Touch can signal familiarity, urgency, or a claim on someone’s attention. Among acquaintances, reaching out without warning may suggest a closeness that has not been established, even when no offense is intended.
A small adjustment in public
Calling someone’s name, making eye contact, or stepping into their line of sight is usually a less startling way to approach. If a touch is genuinely needed for safety or practical reasons, keep it brief and gentle; relationships and situations differ, so this is a matter of social expectation, not an absolute rule.
The useful travel lesson is simple: when you are unsure how familiar someone feels, try a voice before a hand.
