By which I mean people who say ''that is hilarious'' (without laughing)
or they re telling you something and you're like ''I know that already'' after they ve been explaining ( whether obvious or not )for 20 seconds and say ''oh then there is no point for me to explain this to you'' (to which btw I answer ''well, yes', that's what I've just said''. (and I do ask when I m not sure so its not due to a pattern of ''i say i know but then fuck up the work''.
Do you do that to a degree do you know people who do this ? In which kind of situations do they do it? and why do you / people around you do it?
