We can’t control how others will react to us, but we can control how we behave in their presence. What and how we say and share things, how we respond to their requests, what we do when they tell something unexpected, how we are present and listen.
We over-stress about their reaction and pay little to no attention to how we can influence that. We play the part of the bystander when we actually are (one of) the main character(s).
It’s no guarantee that the other person’s will do what we hope for. But we will at least feel infinitely better.
