part

Part of me is very angry, but that part is small. I wrote a letter, and judging by the way everything has been-- she hasn't read it. This means that she is content in her anger. That is ... sad for me.
... But worse for her.

Anger is not a natural state. War is not a natural state. Men (people) are only able to enter war by going into a realm of feelings that are outside of the healthy spectrum. She is outside of a healthy area of feelings and I hope that she becomes my friend again.
I will leave that last sentence as that:
I hope she becomes my friend again.
