When people add you as a friend, they have the option to watch you, your skins and articles, but they can choose not to watch you and that's when it's only marked as a "friend", otherwise it will be as "watching skins", "watching articles" or "watching skins and articles"...and you can change your friends list by going to your watchlist and press the edit friends button.
