I thought that these type of arguments are stupid, like why would I need to hang out with people in an office, I've got my buddies for that after work. Later I moved to another country where I knew no one beside my wife, and then I realized that mingling with office crowd is actually the easiest way to expand your social circle when you're in a new environment. Yes, you can do that on conferences or in a gym or clubs, but it all takes more effort for introverts like me.
