Angry Female Body Language
What kind of body language would a female, who had a falling out with a male "friend", have in a crowded elevator toward that male? Does it make any difference if the male is younger? Can you tell from the body language if the relationship was physical?
Every person is different, but a likely body language shown would be to have the body pointed away from the male friend. The feet are likely pointed to the elevator exit.
I also expect a closed body posture, so arms (and sometimes legs) crossed, shoulders pulled up slightly.
The face would most definitely show tension (lips pressed together, frowning, eyes wide open), or if she doesn't care that others can see her issue with the guy, she could look downright angry.
Age has nothing to do with it. And in this situation, I think it's very difficult to determine a physical relationship. The anger would probably drown out any signs to that affect.
Thanks for asking!
