After sitting and walking meditation, we shared a section from the book Difficult Conversations that talks about we argue and why it doesn't help. Here's an excerpt:
If the other person is stubborn, we assert harder in an attempt to break through whatever is keeping them from seeing what is sensible. If the other person is naive, we try to educate them about how life really is, and if they are being selfish or manipulative, we may try to be forthright and call them on it it. We persist in the hope that what we say will eventually make a difference. But instead, our persistence leads to arguments. And these arguments lead nowhere.
