A sin

When i look back upon my life
It's always with a sense of shame
I've always been the one to blame
For everything i long to do
No matter when or where or who
Has one thing in common too

It's a...
It's a...
It's a...
It's a sin.

At school they taught me how to be
So pure in thought and word and deed
They didn't quite succeed
So i look back upon my life
For ever with a sense of shame
I've always been the one to blame

It's a...
It's a...
It's a...
It's a sin.
