End the day with enough kindness that the people beside you are willing to begin another together.

How a day ends sets the terms for the next one, more than anything that happened in the middle. Unresolved sharpness at bedtime does not stay where you left it; it becomes the mood of the morning, and after enough of them people start bracing rather than looking forward. This is not about resolving everything before sleep.

Before the house goes quiet, say one warm and specific thing to whoever is there. If an argument is unfinished, say that you will come back to it and that you are glad they are here.
