We left some lights on by mistake. The police were sent to check on us: after one day for me, two for my neighbour. Neither of us knows who rang. You cannot buy that.
How long before a neighbour, or a stranger, noticed you were in trouble?
If the honest answer is weeks, that is worth knowing. It is not a judgement on you. Most of us live further from real people than we think: we hear no babies cry and no one cough.
Shortening the answer
It is built from small touch points. Bake for a neighbour. Give each one a plant with your details on the label. Leave a key with someone. Use the local builder, florist, hairdresser and bank. Say hello and goodbye. Pick up the litter by the bins. None of it costs much. All of it adds up.
A man only becomes significant as part of a community, of any size. relations.guide is about the difference between contact and connection, if that is the gap.
