I think it’s the friendship stuff presented on here that feels most alien to me. I don’t think I’ve ever had a major falling-out with a friend of the kind regularly detailed on here. I’ve never lent a friend money, or not since my teens. I’ve never had some big issue about a wedding, being/not being a bridesmaid, attending a hen do. I’ve gone on holiday with friends with all our children, and it’s been unproblematic fun.
If I don’t hear from a friend for a while and they aren’t responding to messages, I assume they need some time and don’t throw a strop about ‘being ghosted’ — am happy to hear from them when they feel like getting back in touch.
No one ‘owes’ me friendship — when I lived somewhere I made few friends and where the baby groups and later the school run were unfriendly, I recognised I was just a poor fit for the kind of people to be found locally, and they for me, and made friends at work, rather than shrieking about cliques and PTA alpha mummies. (Then I moved.)
I don’t view friendship as a service quid pro quo — if I’ve chosen to help or support someone, within my abilities, that’s my choice. I don’t expect some kind of equivalent back, or regard it as outrageous that someone I helped does not always include me in invitations.
