Root Cause
The wai (ไหว้, palms-together greeting with slight bow) is hierarchical in Thailand: the position of the hands and depth of bow signal the relative status of giver and receiver. Adults wai monks fingertips at forehead; juniors wai elders fingertips at nose; peers wai chest level. Adults do NOT wai children first — initiating wai to a child reverses the social order awkwardly. Thumbs touch chin (peer), nose (elder), forehead (monk/royalty).

-
92% success Default greeting to peers / new acquaintances: palms together at chest, slight bow, 'sawasdee ka/khrap'. Wait for the older person to initiate; mirror their wai height.

92% success For monks: thumbs at forehead, deep bow. For royal portraits or imagery: same. For elders in business: thumbs at nose, moderate bow. Never wai with one hand or while holding objects; put items down first.

90% success Children: respond to their wai with a smile and verbal thanks, no wai back. Service workers: nod and verbal thanks suffice.

Dead Ends
Common approaches that don't work:
-
Wai a Thai child first as a friendly greeting
65% fail
Adults receiving wai from children, not the reverse. Initiating wai to a child confuses the social order and the child often awkwardly waits for an unspoken cue. Children should wai adults, not vice versa.
-
Wai a Thai monk with hands at chest level
70% fail
Monks receive the deepest wai: thumbs touch the forehead with a deep bow. Chest-level wai to a monk is read as disrespectful. For royal portraits, similar deep wai applies.
-
Wai a service worker (waiter, shop assistant, hotel staff) on every interaction
40% fail
Service workers wai customers; customers do not wai back routinely. A nod and 'khob khun ka/khrap' (thanks) is sufficient. Returning every wai is read as either over-eager tourist or status confusion. Save your wai for greetings, apologies, or thanks for genuine help.
