Quote #4
His auburn hair had grown shaggy and unkempt, and a reddish stubble covered his jaw, making him look older than his fifteen years. "Sometimes I think they know things... sense things..." Robb sighed. "I never know how much to tell you, Bran. I wish you were older." (38 Bran 5.19)
Robb feels that he can't share with Bran because Bran may be too young for these crises. But in fact, Robb was probably too young for these crises when he started dealing with them, too. The simple act of encountering them matured him pretty quickly.
Quote #5
Robb seemed half a stranger to Bran now, transformed, a lord in truth, though he had not yet seen his sixteenth name day. (54 Bran 6.35)
Bran loves his brother Robb, but sometimes he feels a distance when Robb is self-consciously being "Robb the Lord." Growing up changes people and their relationships, but can coming of age ever separate family? What do you think?
Quote #6
And even the other Burned Men feared Timett, who had put out his own left eye with a white-hot knife when he reached the age of manhood. (57 Tyrion 7.11)
In the Seven Kingdoms, there don't seem to be a lot of adulthood rites. No bar/bat mitzvahs or confirmations. What we have for most people is an informal set of goals, like becoming a squire or having sex (see Tyrion's story of Tysha for that). But the Burned Men Mountain Clan has a very specific adulthood rite: self-mutilation. It's one of the few things we know about that culture.
