The repetition of the idea that he will slowly become more and more imperfect as the years go by emphasizes that he will not be able to give his partner everything he is able to provide for her now, but he knows even when he is much older, even if he is not famous anymore and can’t play the guitar for her anymore she will look past all these imperfections and love him for who he is. By writing this the speaker shows another important value in a relationship, which is that love is everlasting. This pushes me to reflect on the theme of commitment and that one should be ready to love their partner for eternity no matter what may come their way.
