Who is a friend?

My definition of a friend, a person that understands me thorough and thorough that when I mumble or jumble he would understand exactly what is going on and ready to always assist in whatever capacity. A person that I can trust enough to share secrets with and help each other financially and materially. A person that takes my home as an extension of his. A person that calls me by my native name and not some form of nicknames. A person that is always with me when my level is at 0% and when it rises to 100%. A person that would always talk good of me at my back and scold me directly, without meaning any harm, should I derail. A friend is that person that wouldn't join others to downcast me in my absence, he'll fight my course as though it was his. A person that genuinely want me to excel and would pass any information across to me that can be helpful.
