Hi Alan,

Could you explain the reason why behave easily was not possible in this sentence for a certain situation?

Thank you.

Hi,

'Behave easily' doesn't really make sense. Easily as an adverb conveys the sense of doing something without any difficulty as in: She easily completed the race in five miutes. Here 'let your hair down' describes what you do when you are not worrying about what people think and in a sense you relax.

Alan
