To walk or stand in 'single file' means to form a line where people are positioned one behind the other. It's like a human conga line but without the music and coordinated steps. Think of it as a space-saving formation when moving through a narrow area. Unlike a crowd, single file emphasizes order and linearity. It helps maintain control and prevents congestion. It's the opposite of a free-for-all. πΆββοΈπΆ
