I live in a large village. We have the usual Facebook groups with people moaning about dog poo and kids playing, but there is also a lovely community spirit.
There is an old man with Dementia who lives in the village. He is fiercely independent and insists on going to the local shops to get a paper everyday and often gets lost or confused.
The whole village seems to look out for this guy. Everyone knows him and where he lives and points him I the right direction then posts on Facebook to let his carer know where he is and what direction he was going at what time.
Kind of melts my heart a bit.
