A poignant tale of love and regret, this song takes us on a journey through the singer's past relationship. He paints a picture of a man who tried to fit into a conventional lifestyle for his partner – cutting his hair, working regular hours, even changing his drinking habits. However, he confesses that he was never the 'Sunday morning man' she wanted him to be. The lyrics reveal his struggle with commitment and settling down, despite coming close with her. His inability to ask her to marry him shows his fear of being tied down. The recurring line about wanting to know what's behind the other door indicates his constant search for something more or different. Ultimately, it's a song about lost love and the one that got away because he couldn't stand still long enough to truly commit.
