When people have pointless angst over Teams/text, I reply saying something along the lines of "I think you've accidentally left the caps lock on".

If I am sitting at home, usually I am yawning and scratching my privates.

If in office, I make a apologetic face but am smiling in my head imagining him naked while shouting away. Once he is done, go out and catch a ciggie with someone.

Either way, no need to take stress more than 3 minutes if you want to continue working at a firm.
