How do I keep others' grief from affecting my own home?

You can untangle any family law knot, and the cost is that you carry other people's grief home, until it colors how you see your own family. That's not weakness. It's what happens when you spend your days close to people at their worst. The care that makes you good at this is the same door the sorrow walks through. But the families you see are the ones that came to you because something broke. They are not a fair sample of your own home. Your mind, soaked in conflict all day, starts expecting it where it isn't. Naming that is the first step to loosening its grip. Build one small ritual that marks the end of the workday, before you walk in your own door. Leave the cases on the far side of that line. You can hold others' grief at work without letting it decide how you see the people who are actually yours.
