I shan't say that I understand all of that, exactly. The theory isn't my strong point; it's a simple matter for me to transfigure a table into a tree, but far more difficult to write an account of what exactly became of it as I did. But I really am sorry about your father, and about the accident. It is a pity that I shall never have the chance to meet him.
It's alright to be sociable without any great obligations on either side, isn't it? I don't think I could stay entirely alone without even that.
