What does it mean if a women stands really close behind a man?

Answer 1

Potentially she is queuing for something, if there is another person behind her. Alternatively she wishes to be trodden on - e.g if the man turns around quickly. Possibly that she is to shy to ask you something directly, so chooses to approach from behind. Alternatively, approaching from behind reminds you that you have a blind spot, and to look over your shoulder - it's a reminder of weakness.

Answer 2

If a woman stands very close behind a man, it could mean a few different things depending on the context. It could indicate that she is attracted to him or trying to flirt, or it could be unintentional and simply a result of crowded space. It may also be a sign of assertiveness or dominance, depending on the situation and the dynamics between the individuals involved.
