Actually I have gotten sick of him.
But, maybe I was the same as him in some way, when I was a member of site A.
However, at least I didn't blame other people nor offend them like him.
I am really surprised at his way. He believes that he is the most miserable person in the world, and that he is suffering from evil exploitation by his company.
I was really astounded by how he changed his attitude toward his boss very dramatically from unthinking faith to strict attack. I understood that he always prioritize himself any time. He just looks up those who support him and looks down those who have a different opinion from his.
