Ive got an old group of friends, 7 of us from uni. The others seem to make a lot more effort with one another. A few of them often go out on a night out that I know nothing about , a few of them have recently been away together, I tend to only really be there if it’s a bigger group gathering for an occasion. I do see one of them very very rarely alone.
I think as I’m writing this I know the answer. I’m the one no-one particularly likes aren’t I!
