Contrary to popular belief, sound of it and the glamourousity of the artist who sang it (Savage Garden), it is actually a pretty sad song. Well, at least, in my interpretation.
The song tells about a girl who was not loved by her parents, neglected and possibly abandoned by them. She never knew what love is, never 'felt needed', and befriends other street kids who are equally poor with no moral guidance and survive by crimes. But deep down inside, she longs to be loved, and is willing to do anything, even 'flying to the moon and back' just to have somebody who loves her.
And there's another similar story line in another popular hit by Red Hot Chilli Peppers. Dani California was born poor, possible out of wedlock (my presumption, from the lyricist's description of her 'hippie' mum and 'copper' dad) and she survives by committing crimes like armed robbery and others. She finally died at a young age after she was shot during one of her missions.
I was just thinking of the reality of these two songs. There are many young girls out there, longing to be loved, to live a normal life, and basically, to be accepted.
I wish I could help. Not out of pity, but out of love for humankind. But can I?
