I have 2 jobs, one full time and one part time. The boss at my part time job shows most of the the signs of being a psychopath. Also, he wears sunglasses indoors. The full time job is completely online as an automation engineer so most of my interaction with boss is via voice chat and when he gets grumpy it kind of takes the sting out of it because you can't see the anger in someones face and body language.
