What does it mean when someone always signs their letters Love me?

* Whether it's a mate or a good friend 'love me' is just a cute quirky saying, but it still means they love you and just don't add their name because you know who it is already. If you remember the movie 'Ghost' with Patrick Swayze and Demi Moore, she would always tell him she loved him and he would always reply, 'Ditto' (meaning he felt the same, but he just didn't say the Word 'love.')
