Billy was a good friend of mine   We grew up together ever since we were nine   We went to school, he was my best friend   And I thought our friendship would never end      In high school he played football   And me, I didn't do anything at all   He made touch-downs, while I played pool   And no one could figure out which one of us was the fool      Then we both went to collage   He studied medicine while I studied foliage   He got a's and I got d's   He was going for his ph.d.   Then I decided to drop out   Things were getting a little too hot   Billy stayed there, became an intern and then a doctor   Then war broke out and he had to go   But not me, I was mentally unfit, or so they say, so, so      When he came back, he wasn't quite the same   His nerves were shot, but not me   Last time I saw him, I couldn't take it anymore   He wasn't the billy I knew, it was like talking to a door      Billy was a friend of mine   I grew up with him ever since I was nine   We went together through school   And now I often wonder, which one of us was the fool
