Saw her sing this song in a show on TV. Love her lyrics. As we grow up, face different difficulties, we might get hurt and lose that innocent 15-year-old heart. However, this song encourage us to never give up, and keep/find back that innocent us :) No matter what life may offer, you can close yourself up, never believe in anything or anybody again OR you can face it with that simple, clean, innocent 15-year-old heart and find relieve. It's a choice actually :) Stuff in the past can't continue to hurt you unless you let it.
And this song reminds me of the quote:
Dance like nobody's watching
Love like you've never been hurt
Sing like nobody's listening
Live like it's heaven on earth
- Mark Twain -
Starting to like Rene and find her songs' lyrics very 'weighted'. Also, when she sings, she's like toking to you with her song. Its like her eyes can tell story :)
