Brother 

The best person in the world.
He's such an idol to his sisters.
Brother is the best.

Bryony (Sister) - BROTHER, you're the best.
Kerry (Sister) - Yeah! You're our idol!
Sean (Brother) - Aww thanks guys. You're the best sisters.

That's an example of a good family relationship.

Brother 

A brother is someone who may or may not be related to you but you guys are family. Through thick and thin, y'all are always gonna be good. They irritate the fuck out of you, but they also make you laugh, protect you, and offer a shoulder to cry on. They are always there for you no matter. They also will beat this shit out off anybody that needs it.

Her: I love my brother

Somewhere a girl might put you as a best friend and someone can trust. It is very hard to get out of this relationship, however she may in the long run finally ask you out.

Jack and I are like brother and sister, however he is my best friend.
