Which Way Does ln -s point (or Which Comes First, the Real Folder or the Symbolic One)?

I hate "ln -s". I can never remember which to put first -- the name I'm creating or the name which already exists.

ln -s {target-filename} {symbolic-filename}

or

ln -s {thing-that-exists} {new-thing-that-will-exist}

or

ln -s {old-thing} {new-thing}
