Saying "Hush" and "Shhhh" and "Be quiet" are perfectly fine, but saying "Shut Up" is just such a horrible thing, apparently! But don't they all mean the same thing?
I know that "Shhh" is starting to become an impolite thing now, because it was used so frequently, as an alternative to "Shut up".
If "Hush" were used so frequently, would it, too, become a 'bad' thing to say?
I am asking this because recently, my fiance's little brother was being very annoying. While I was trying to work on a project, he kept spouting off all this stupid sarcasm and jokes (And, as an Autie, I dislike sarcasm and jokes, and he knows this.)
I told him, "I am busy working on this right now and I would like to be left alone."
So I took my project into my room and closed the door so I could work on it quietly. (I was trying to figure out how to build a Macro Photo Studio out of pvc pipes.) He opened the door, stood at the doorway, and continued talking and talking, as if he hadn't heard me at all!
So finally, I told him, "For goodness sakes, will you just shut up!"
And then with a hint of hurt in his voice, he said, "Jeez, fine!" and ran away crying to his mother, and proceeded to tell her that I told him to "Shut up." He was actually crying!
And then his mother came in and sternly told me that "Shut up" is a bad and hurtful thing to say, and to use words like "Hush" or "Be quiet" instead.
Never mind how annoying and rude little brother was being!
