My neighbours have children who play in the gardens with their noise at an acceptable level and sociable hours.
Nobody is inviting guests round for BBQs.
Nobody is doing noisy DIY at unreasonable times.
They WhatsApp the rest of the street to see if anybody wants something picked up at the shops. No judgement if it's something non-essential like alcohol. They pay immediately by bank transfer.
The dog owners aren't walking their dogs 5 times a day because their dogs are special.
The houses with young children often stick pictures in their windows which cheers up the neighbourhood.
People are rarely leaving the street. (I can hear cars driving)
If someone is short on milk or whatever, there's lots of volunteers who are happy to drop some off if they have extra.
Nobody is parking so that the bin men and emergency vehicles can't drive past.
Everybody is sharing info like if they see a local shop getting a delivery.
I live near a local tourist spot and can see that the car park is empty.
