These are the strangers you see most and know least: the woman who hangs the recycling bin back on its hook, the driver who steers a forty-thousand-pound truck through your cul-de-sac without scraping a single mailbox, the Amazon kid sprinting up your walk in 99-degree heat. They keep your week working. They are almost always thanked with nothing.
A cooler by the door turns “I should do that sometime” into ninety seconds. Refill it on Sundays. Do it for a year. Eventually you will know the names. Eventually they will wave first.
