The porch light left on until you got home was a whole paragraph of love nobody said out loud.

A light left on is a small act of waiting. Somebody stayed half awake and arranged things so you would not come home to a dark house, and it went unmentioned, because saying it aloud would have turned it into a favour. Families pass enormous amounts of information through gestures like that instead of words. The gesture reads as nothing until you know what you are looking at.

Look for your own household’s version of it this week. Then thank somebody for one of those things specifically, out loud. And leave the light on for whoever comes in after you.
