Wall Halla
Posting to a friends wall on FaceBook.

Oh, John, I finally found you after all these years. Good to see you, your family, all your friends, your pictures, everything else your interested in, and if you don’t mind please post a recent picture of yourself so we really know what you look like. Post a “Wall Halla” now and then so we know what your life is really like.
