Am a little stumped by this one I confess as usually once a song has a meaning attached it tends to stick. Okay after staring at the screen for a while and hitting random songs in my I-Tunes I have a tenuous answer. This is more a question of me understanding more rather than personal feelings regarding relationships, maybe rather fitting given what today is. The first is about the way what you would do for love changes as you grow older, as teenagers we are more willing to become what the other person wants of us rather than remain true to ourselves and risk being rejected.
The second song is one I loved from the moment I heard it but as a person in my teens when I first heard it I could not understand the concept of needing courage to walk away from a relationship but as an adult I can see the consequences far more clearly and know how scary it could be to make that move.
