I know someone like me this but a bit older. They are a relative of mine.
Lived in the same place their whole life, only ever move a mile or two within that same town.
Retired from the same job they got after leaving school, never promoted.
Been abroad once. Always went on holiday in the UK, eventually got a caravan.
Same friends long-term- still has friends from primary school, secondary school, their job. On good terms with all their neighbours.
They left home to live with the only partner they ever had, who did loads for them. They never learned to drive. Their social life was visit family once a week, be visited by family once a week, see friends once a week- alternating weeks between work friends and school friends.
They cared for their partner who was blind and unable to walk for the last two years of life, even though they were themselves elderly by that point. Did absolutely everything for them. They were both supported during that by a rock solid network of all the long term connections they both had. Neighbours and friends who would help out.
The partner recently died and they have received so much help and support during that time. They are also very well set financially, because although they never earned a lot, they only ever really spent money on their house. Their partner did earn a bit more, but not much and they bought a wreck together and did it up.
So there are benefits of being like that as a person, and with being with someone like that. Personally, I am very fond of them but find it easier to only be around them occasionally for short bursts as they are very set in their ways.
If it’s not for you, it’s not for you.
