Hello. Would you tell me what the phrase "fall in behind him" means in this context below?
Please help! Thank you.
And his friend used to hang around while Noi repaired the fence or played on the swing or fell in behind him and they chatted away until, Poof! He disappeared as suddenly as he had appeared.
Joined him without seeming to - walked close enough behind him to seem to 'belong' (without greeting him and risking being reuffed or ignored). 'Fall in' has a similar - but not identical - meaning in a military context: to become part of a marching/parading body of men/women.
