I promise I won't leave you. I promise I won't have a change of heart. I promise I'll keep my word. I know I'm faithful and loyal and keep promises. I know me. I can promise. You can't promise you won't leave me. You can't promise you won't have a change of heart. You can't promise you'll keep your word. I don't know if your faithful and loyal and keep promises. I don't know you. You can't promise. It should be the same way in your eyes as it is mine. In my eyes, I'm the one who can promise. In your eyes, I should be the one who can't promise.
