I have a good friend we will call A who has a partner, kids, a business, animals, and a hobby.
Another one of her friends B (who does not have a partner or children) is berating A for not having enough time to spend with her.
I wish I saw more of A but I know she is busy. I am busy too: we live two hours drive from each other. We chat when we can on the phone and WhatsApp each other.
As my life has gone on I realise that friendships wane and wax for that matter, new people come into my life, but that few people are deliberately thinking "how can I piss this person off?"
They are just trying to juggle everything that life is throwing at them.
