I have loved you for three years, and you might give me a lifetime?
I have loved you for three years, can you possibly return me a thousand days and nights?
I loved you for three years and maybe the next three years.
I have loved you for three years. I don't want you for the rest of my life. I don't want to spend a thousand days and nights with you. I just want you to come over and show me your face.
Please don't, don't just show me your declining back.
