[Perihelion]

I'm in no way suggesting that people spend all of their time at work or have significant overlap between their work friends and after-work friends. However, it's nice to work with people and not robots. Some people can tolerate sterile work environments devoid of anything but neutrality, and some people can't. I'm not even saying you have to be friends with the people you work with, but being friendly goes a long way. You spend a large portion of your day with these people, so it's not a huge ask for someone to give a crap about them as people.
