I think I've been a bit stupid about all of it, just thinking it didn't matter.
It doesn't if the friendship's real! Sounds to me like it was to you, but your 'friend' had a chip on her shoulder a mile high, and was trying 'to keep up' rather than keep a friendship. (Am a brassic L/P btw)
The school thing is funny. We got publically cut out when almost everyone else's went to independent and mine had no choice but stab vest high, (it's locally known as that) and when we started home educating it was like we'd
failed further.
We carried on being in the same spaces as everyone else but cold shouldered. It really hurt and was humiliating.
There where a couple of decent people who said encouraging things and didn't treat us as total lepers but we were socially excluded out of all groups.
It was that couple who were genuinly pleased for us who probably spread the news when exam results showed mine taking harder exams and doing well, and there was a just as sudden change as the cutting us. Suddenly people who've not even replied to "morning" for years, started coming up congratulatng and inviting to things again.
It's weird and disorientating, and I don't know what to make of it other than while I have no problem seeing them suceeding, I think they had a problem with what they saw as seeing us 'failing', and it sounds like a sort of inverted
situation with you and your friend.
