If you talk to a girl and her feet points to another direction where the exit is, then I have some bad news friend.

But if you talk to a girl and her feet points directly towards you, then you wonder if there is something behind you right?
You check for some clarity.
Because their might be a chanse that you are blocking her from reaching the exit right? You should know though, it is the place you came from. And while you check she is already towards that exit. You see this and you observe her. Thinking all sorts of biological imperative stuff, in the simple way. The door she will be going trough opens. And in that exit, there I am bro. And I leave the door open so she can pass, as the gentleman I am. Then I walk towards you after I closed that door.
Me: Did you check the validity of the psychology rule?
Did you want check out if she was interested?
You: No response
Then I smile and I leave your vision.

And you realise the answer when I past you, leaving you questions similar to that mind of yours creating all sort of answers to fill up the validity.
You did not look back...
