I have really close friends, all females. I don't know if we're best friends but they're the closest I've got 🤷🏻♀️
I don't have male friends mostly cause in my field of studies they're very few. I had one in high school but we grew apart along the year, going in different direction.
Except the 2 closest friends I have I'd say my brother and SIL are my closest friends too.
I don't have many friends, so those I have I consider like best friends. Other people are "friends" but more because of classes so more like friends from opportunities (don't know if that makes sense 🤨)
