yes i always got this feeling, would be talking a lot etc joking "connecting", BBBBBBBBBBUT ABSOLUTELY NO EXCHANGE OF SOCIAL MEDIA, OR PHONE NUMBERS email.
ITS LIKE OUTSIDE THE WORK OR SCHOOL YOU DONT FUCKING EXIST
ABSOLUTELY BIZARRE THAT THESE NORMAN CRETINS DONT WORK OUT THAT YOU ARE AWARE THEY ARE SOCIALLY REJECTING YOU AND THAT YOU KNOW THEY ARE JUST USING YOU TO PASS THE TIME AT WORK OR SCHOOL EG BEING THEIR JESTER FOR THE WHILE.
This is why i only do this angle of being nicey nicey and chatty and whatever for a little while
If after a week or so they dont ask about outside of work/school what are you up to, what was your weekend like eg social questions, dont ask for any social media, email phone number exchange, i know its over and they are clowning and simply using for their own ends with nothing coming back.
Then i just ghost the shit out of them one word answers, literally fuck you, if im not good enough outside the school or work environment im not interacting in it either.
Its like there is some kind of mystical force which stops any interaction outside the specific environment where you initially met
