Offer to set up a MealTrain for a neighbor having surgery.
Put a “swing on me!” sign on the playset your teens don’t use.
Join your neighborhood list serve, listen to what people are saying, asking for, talking about. (don’t have one? start one!)
Make time in your week to dictate a voice memo to a friend who you miss. If your schedules are too wild to connect IRL, set up a time to chat by phone.
Let’s all STOP buying and extracting stuff and invest in living breathing people.
