... bluff charge is by definition aggressive behaviour. So when does it happen? Rarely. It's not like they see you and want to bluff charge you. You have to be seriously encroaching on them or their cubs for them to even care.

And it's even in the name: bluff charge. They don't want to fight, it's a bluff. They want nothing to do with you. They want you to go away. Even most of their aggressive behaviour is trying to get you to simply go away.

So returning back to normal behavior, yes they are chill.
