I'm thinking about a girl that used to know And her sad sweet smile L can't help thinking that l miss her so And her sad sweet smile I'm thinking about her, can't help thinking about her How could l have known there was no one home Behind that smile How could I have known that she lived alone Behind that smile How can I pretend that l never knew That sad sweet smile L couldn't have held back if l wanted to From that sad sweet smlle Each time I fear l'll find that all my loves' in van And each time l say l'm through yet here I go again I'm searching for a girl and one day l'll find A sad sweet smile For l know what I'm looking for lies behind A sad sweet smile
