I don't speak Thai, but some online sources gave me these definitions: "[to] be afraid of offending (someone)" "[is] reluctant to impose upon; deferent to; is considerate of (another's feelings); respectful of (another's privacy, space, etc.); fearful to approach" "to be afraid of offending (one),to be considerate of another's feeling" "be (too) courteous, be considerate, be afraid of offending, look up with great respect" I don't know which one is the best definition, but they're all very similar. I don't think we have an exact word in English for this feeling, but perhaps "deferential" or "reverent" would be the adjective you want.
