You'd talk to her about picking battles and the time/place/way we talk to people to try to make our points.

And I'd wager most all of us have acted out in a way that caused a parent or mentor to have that conversation with us and hopefully we grew from it.

It's awfully tempting to trivialize the battles "the new generation" wants to fight and write them off as entitled brats but I think when you write people off that way you're making yourself as irrelevant to them as you think they are to you and it doesn't do anything to help either group besides make them more resolute in their antagonism.
