My ex-debutante mother trained my siblings and me to be good hosts. She also trained us to be good guests. We brought bread and butter gifts. We found something to compliment in every home. We ate whatever food was placed in front of us without complaint and insisted on helping with the dishes.
We were groomed to make social occasions run smoothly, with nary a scene. White Anglo Saxon Protestants (i.e., WASPs) with social pretensions avoid conflict and HATE scenes. They are a symbol of ugliness and failure.
And so common.
