OH my gods! I am sooooo guildty of this! I write Faramir as the fragile one, the one who knows the higher Elvin language of Quenya, the one who isn't very good at soldiery type things unless he has to be.

I write Boromir as the blithely dummer brother who, though he is older and very protective of Faramir, has no idea about poetry, literature, or anything related to the scholarly world.

Funnily enough, when I write Aragorn, he is very, very good at both of these types of things. Hmmm...
