How concerned would you be if your chats with your best friend got leaked?

At this point, I consider the chats with your best friend more intimate than your own personal journal. Names are being said, tea is being spilled, crashouts are being registered, and all your worst pictures are probably stored as stickers. There comes a point in your friendship where messages start sounding like you too are absolutely insane, and there is no cure for your delusion. Context starts becoming optional, and suddenly you go from criticizing your ex to expressing how grateful you are to have them as a best friend.
