You MUST learn the lyrics to this banger. On the walk, recite these lyrics to him. It will subconsciously get in to his head. The best thing about this is that you need to take a tape recorder out with you at all times, so when he recites them back to you (subconsciously) you can show him the evidence and emotionally blackmail him in to proposing to you. Don't believe me? Why do you think my surnames not "Flowingperiod" anymore?
