Maybe it tell us that the good friends sometimes don't come by the great things that they can offer to us, instead they come in small things... (which for me are greatest things) like hugs, smiles, talking, some times a "How are you?" or " Do you need something?" ... or something that makes you better when you are in needing of that! :)
