I, who have no sisters or brothers, look with some degree of innocent envy on those who may be said to be born to friends.
A sibling may be the keeper of one's identity, the only person with the keys to one's unfettered, more fundamental self.
There is no love like the love for a brother. There is no love like the love from a brother.
Brothers are like streetlights along the road, they don't make the distance any shorter but they light up the path and make the walk worthwhile.
Brothers are like stars. You may not always see them, but you know they're always there.
