I never had a little sister  No brother to tell my troubles to  My nights were oh so sad and lonely  Until the day that I met you     Some people say it isn't healthy  To be the only one around  That's why I get a little edgy  Don't want to lose what I have found  'Cause I'm an only child     You are the light at the end of the tunnel  You are the sun and the moon and sky  You are my sister mother lover  Without you, babe, I'm gonna die     Some people say it isn't healthy  To be the only one around  That's why I get a little edgy  Don't want to lose what I have found  'Cause I'm an only child
