This is one of the first and especially one of the closest, with that of parents. But unlike the latter, fraternity is more a relationship of complicity, evolution and deep friendship.
Of course, we do not argue the same way as with a friend and we do not get along in the same way as a couple. But to break the bonds between brothers and sisters is to lose a part of oneself that we have built together for a long time.
Even if we get mad for nonsense, I love my two brothers and my sister and I hope that it will continue until the end.
Very appropriate comparison, and would’ve made for an awesome scene in the show.
