They DON'T have a bad relationship, that's literally normal sibling bickering
For adults though? As I said, I know TEENAGE siblings, including my own situation, who bicker way less and don't even get me started on the adults, they're usually basically just buddies who grew up together, and the thing with their mum??? Who on earth brings that up and has a physical fight (no matter if unserious) over it in their 30s-40s
I would agree if they were children but c'mon now
