This is my interpretation of the song: "Life for rent" by Dido

When the singer mentions that she has not  a place to call home, is because they are not attached to anything

She apologized for not being in love, because usually in our society, we fall in love, and if not then we are abnormal

To say that life is for rent, means that one is not living his own life

We are so used to want so many things that we feeling own everything we have, when really everything in this life is temporary, nothing is forever

When we are afraid we can hardly achieve our dreams.
