People, close or not, took me for morose on frequent occasions, and somewhat of a nut job, which became practical. Sometimes it’s really good to left alone because of your behaviour. But most of the times it’s simply a generic and practical form of rejection. One becomes accustomed to it, I guess, and after all, loneliness is a multipart concept. It is never built by a single element.
And that is why it might become so difficult to kill.
