"Mrs. Maybe" takes indecisiveness to a whole new level. If you've ever had trouble committing to anything, including committing to nothing at all, this song is for you. Heatley tell us: "'Mrs. Maybe' is about a relationship that had no clear beginning and no clear ending, about a boy who kept showing up then leaving and I kept letting him. It's about wanting to leave things open ended, never truly leaving, and never truly staying either."
