Watch for the change in an older neighbor’s routine without treating their life as yours to supervise.

Living near someone gives you a kind of information nobody else has: the curtains that always open by nine, the walk to the shop on Tuesdays, the car that has not moved. A change in that pattern is worth noticing, and noticing is not the same as taking charge. Being watched over and being watched feel very different from the inside.

If a routine near you has shifted, knock and ask an ordinary question rather than a diagnostic one. Offer something specific and small. Let them tell you what they want, and take that answer seriously.
