while it is crazy, I have seen past managers and even the current one very happy and grim smile after see his/her people suffering, they love it to see someone suffering..
mostly he will read a set of words to you , however, when he turns around to go out the office, I can see his face smiling with a grim gesture when turning around walking out.. it is just I stand up fast enough to catch the side of his smiling face, He was trying to hide from me..
damn, what kind of people are they? this manager moved back to UK/Europe after several years and joined some other companies.. to coast into his retirement.
