I'm perfectly fine with communication at work. And that is the only thing that matters to me. There has to be a point for me to talk, otherwise I see it as a waste of time and energy. I do not have the need to connect with people, so I guess that's why being like this is easy for me. My most miserable moments in life was when I felt like I had to be social, since I've dropped that toxic way of thinking (IMO), I'm much happier. I hope this makes at least a little bit of sense.
