It's easy to notice what's lacking. It would be great if he did more work, she offered this, or they would listen. Demanding improvements is one way to let the other person/people know what they are lacking (or at least perceived as lacking).
And the alternative to demanding is offering: holding a space to listen and understand why he didn't do the work, she wasn't willing to offer, or they refused to listen and connect. When we shift from demanding to caring, we change how we show up for others.
All along, the change we hope to see doesn't start with other people, but with ourselves. First.
