I actually think it’s quite surprising that your surprised op. There have been stories forever of bodies being found in homes and no one missed them. The lady in London who was wrapping Christmas presents before she died, they must of been for someone but it was over 2 years before her body was discovered.
There was another lady who had schizophrenia who had alienated her family apparently, obviously not by choice, but again it was years before her body was found at home. These stories come out all the time.
We also live in a society now where people work longer hours, further distances from where they live, fill their free time full of events and activities making it harder to make new attachments and friends, or even notice other people.
I’ve always been a sociable person who no matter where I live would know most if not all my surrounding neighbours by sight as I’d take in my surroundings. Not these days, there are loads of houses around me that I would not have a clue who lives there, I might know which car belongs to which house but couldn’t pick out the person who lived there. I remember during lockdown wondering who all these people walking past my house were, they were neighbours who I’d never seen before because they were obviously busy people who were never home, im a SAHM so home a lot, I’m also the go to house for couriers as most know I’m happy to take parcels in and still I couldn’t tell you what some of my neighbours look like.
I do know the elderly lady who use to live behind, she had slowly alienated everyone in her life with the exception of her daughter who tolerated her. Her son, daughter-in-law, son-in-law and grandchildren all cut her off so after her lovely husband died she was all alone. She had a nasty fall, I saw her one day through her window looking all battered so knocked on her door to see if she was ok. No one knew about her fall she’d tried to dress her cuts herself. Her daughter was on holiday and she had no one else to call. She kept telling me she was ok but I couldn’t leave her but struggled to know what to do. I remembered her husband was buried through the local church and she always had a Jesus is risen sign in her window at Easter so figured she’d had had some connection with the church. The parish priest knew her, but even he wouldn’t go to her because of some reason. He was able to make contact with her son though and he arranged for someone to see her and take her to get checked. If I hadn’t have parked outside her house, which I don’t normally do, then who knows how long she’d had been like that. She couldn’t remember when she’d fallen or what she’d eaten but the bruises and scabs were at least a few days old. She was eventually moved into a home about 6 months later.
The sad reality is, there will always be people who don’t have others in their lives for many reasons.
