actually feeling this thread massively right now.. most of my friends from primary school came to high school with me, I have other people on facebook but never really spoke to any of them apart from those who came to my HS.
mostly technological issues, but my phone has very little storage so I got rid of all my snapchat, viber, whatsapp communications.. my close high school group was only really in contact through whatsapp so I lost contact with most of them since starting uni. only one of my high school friends came to Monash with me and she knows my atarnotes friends now too, but apart from that I lost touch with basically everyone from my school life except this girl who I see at uni and my best friend since the 4th grade (who I still only text like every fortnight).
I don't think I really made any friends at uni, there's no one I message about non-academic stuff in my course, I didn't join any societies, I don't like being around people in my breaks at uni.. the only people I talk to anymore are people from atarnotes.. which is weird but pleasant, because though I've never met half of my AN friends, they seem to be all I really have these days and I never really thought they'd be as important to me as they are..
so hey if anyone wants to be friends hit me up <3
