Henry is the coolest big brother.  He was looking at a book today with Walt and pointing things out to him, and as he did, Walt would respond accordingly with "Oh, yes", and other reciprocal replies.  Henry pointed to a boy in a picture and announced that he was once a baby, but then grew into a "Berber" - which is Walter's name for his brother Henry. 

I just think that's so cool.  I remember when Walt first called Henry "Berber" and Henry was not too sure about that name, but then embraced it finally announcing that he is Berber.
