Is the rudeness of most software a reflection of the modern world? I was in the middle of composing an important missive just now when a window popped up in the middle of the screen asking me to allow some officious bit of code to update itself, and when I hit the get-on-with-it button the infernal thing took over the entire screen. In human terms that's like walking into the middle of a group of people engrossed in conversation and shouting "shut up, I'm talking". Makes me feel like beating the offending item about the head and booting it back below stairs.
Correct behaviour would be to utter a polite cough, as befits an underling, then to wait at parade rest at a discreet remove until told to carry on, whereupon it should carry out its duty quietly and with as little fuss as possible, rather than hauling one off by the scruff to observe as it cleans out the commode in Lady Margery's second dressing-room.
It's so hard to get properly-trained staff these days.
