To truly understand a person, sincerity and wisdom ain't enough. You at least need one more ingredient called 'Perspective'.
If you are not where they are, then you can't see the picture the way they see it, and hence would fail to understand their reactions. And your conclusions about them would most likely be wrong.
You would see people say that they are understanding, and respectful of others views; they actually mean totally the opposite. To understand someone else, and to see it from their eyes, is not a choice that you make. Because to be where they are, they spent their whole life. And it takes exactly that: a whole life to reach there, to see it from their eyes, and to understand them. Sincerity and wisdom fall too short of it!
Goodbye friend. I, and Zero will miss you, a lot!
