It always seems in threads about friendship that some people have no trouble attracting and keeping friends, some feel they do all the work with no return in kind and some have few friends. I think English people (maybe not Welsh or Scottish) have always been reticent and so making new friends, real friends, is difficult. Lockdown has changed such a lot and many people have got used to their own company or can't go out for health reasons because they must still self isolate.
I've always been one who has put a lot of effort into friendships without much reward and I've got tired of bothering now. I've noticed as someone else said, that friendships are often based on a hobby or activity and when you can't do that anymore, the friendship drifts.
I agree that some people are users. I still grit my teeth about one friend who moved from London and I listened to interminable stories about the horrors of her move. Once she moved, a mere 20 miles away, she stopped communicating and now she spends her time on Facebook flaunting her wonderful new life based on London money and she's always too busy to meet.
I am also now gunning for the local WI! I was a member where I lived before and it was very friendly and inclusive. The small meeting where I am now are the most cliquey, small minded, unfriendly bunch you could hope to meet!
So, like others, I have some old school friends worth keeping in touch with, some activity related friends and some people who I like and who may be friends but I'm not going to be the one putting the effort in.
For most of my life, I've believed in and wanted to build community, but now I think it doesn't exist in most places. I think lockdown was a moment when a lot of people retreated into their families and didn't necessarily want to get involved with others. It's good to learn to become sufficient I think and then people don't see you as a potential burden.
I should feel good about it but....
