And unless you're having a shit day you probably answer and waste a few minutes. You adapt to them, meanwhile they are always willing to extend the same courtesy.

There is a whole song and dance that has to happen on said call to not be labelled as rude. Have to talk about all kinds of crap not relevant to the task at hand. 

Seriously, I don’t care about your grandkids ice skating competition when I need to finish a presentation for the meeting my manager assigned last minute. 

There is a time for bullshitting and a time for getting stuff done.

Another one loves to bring the water cooler talk to everybody else’s office. Mostly to complain about stuff. Loves to show up minutes before meetings that he is on. Then goes back to his office eventually and logs into the meeting late and asks for others to bring him up to speed. 

Lol.
