How Can You Be Sure?

Seen all good things and bad Running down the hill All so battered and brought to the ground I am hungry again I am drunk again With all the money I owe to my friends When I'm like this How can you be smiling, singing How can you be sure How can you be sure If you walk out the door Will I see you again If so much of me lies in your eyes I am hungry again I am drunk again With all the money I owe to my friends When I'm like this How can you be smiling, singing I don't want you, I don't want you How can you be sure I don't want you, I don't want you How can you be sure I don't want you, I don't want you How can you be sure I don't want you, I don't want you How can you be sure I don't want you I don't want you anymore I don't want you I don't want you anymore
