My sister isn't related to me at all, but we call eachother sister for maybe 2 years now. I lived together with
her in one room for 4 years in boarding school, so it checks out.
We've known eachother for 8 years now and she's the best sister anyone could ever ask for! We first met at an
art contest both of us won. She's always read a lot of fantasy, loved Hamilton and been in a happy hippie family.
She's also really good in academics and she's really smart (and, luckily not only booksmart (although she doesn't
party, drink or anything)), but I've always been better with living languages than her. Her biggest weakness
is probably that she's a bit of a "Besserwisser", which can unintentionally come off a bit rude sometimes, hehe.
However, she's the sweetest person with lots of love for everyone she meets.
