I am, believe it or not (i'm not sure I believe it myself sometimes), socially aware enough to realise that there are different cultures, personalities, etc etc, some of whom believe various actions are "disrespectful".
I get that. I really do. But there's so many things on that list these days. Its what I feel if i'm told to close a laptop when its quite clear i've already made a decision on whether what is being said is relevant to me or whether i have better things to do. I'm also aware of the social power/authority plays involved in such, as well as traditional etiquette.
But i'm also getting to that stage of life where I'm no longer as concerned about whether some numpty feels i'm disrespecting them by prioritising my time against their preferences or being "rude" by being practical.
I'm aware you can't do this in many workplaces/contexts where you basically have to be submissive/concordant with a workplace culture that says otherwise.
But my life is too short for me to worry seriously about such things anymore. I don't go out of my way to offend, nor do i take said actions as some kind of social/political power play. If a person doesnt want to work with me because of that or gets offended, well, rack another one up on the board...
Its not black and white, granted...but I think its more statistically valid that people who make a big fuss about such are more likely to be on my own "waste of time/oxygen" list...
