"Now friendship in those days was a bit different from what it is today; friends did not have to agree on everything and often agreed on practically nothing. They were people with whom you could argue all day and yet never get irritated or angry at all. In today's world we seem to have lost the real meaning of friendship. If someone disagrees with us, it is fashionable today to dislike them for it. This is silly and robs us of the best kind of friends we could find, for if we are always agreed with, we can never have a really serious conversation; we cannot learn from someone who agrees with what we say."
