Yes, I agree, it means whenever you lose somebody, they will always be there, so you can never really say, bye-bye, to them, because they will always be with you. It also reminds me of my dog, and grandfather, they are somehow still here with me, but not in person, or whatever you call it. Whenever I think of it, it kind of soothes my heart, even though it is still hurting, and it probably always will.
