They are as, probably more aware than you of how likely they are to run into you again.
If they know they will keep running into you and you know it, the seeds approach works best in my view.. Give them space
If you both know you are unlikely to see each other again, without planning it, then both of you want to accelerate the process. They are going to be more open and help you accelerate it if they are interested. They know they might miss the chance to be with you if it does not run a bit faster.
Then there are the wildcards that know they will see you again and again and want to accelerate it anyway.
If you watch all of them, you will get an idea of how their mind is going, heck they will even tell you most of the time *if you truly listen*
If you met you, knew you were not going to run into yourself apart from by pure chance again, wouldn't you want to help you meet you again?
How does one balance the indirect communication that is necessary to LISTENING with the DIRECTNESS that is crucial to meeting again?
Is there a concept here or is it just Samba versus Tango dance?
