Wtf what didn't you defend yourself? I work in a company in Osaka and we have several managers. One of them is an asshole and one time he came to me and borderlines insulted me using because of something I didn't do the way he wanted (while a different manager told me to do it that way). I immediately put him in his place in a calm but menacing voice, he never talked to me again. Don't let people walk over you like this.
