You're My Password

I took your face Just so I could be like you You took the place Of all the dumb mistakes You're my treasure I'll keep you safe from the world You're my boy I'll keep you safe from the world But I don't know what to say I don't want to say a thing I've took all the best from you But I've got my school friends mouth I'll keep you in the painting I put above my bed I'll make you pose like Jesus With a crown upon your head But I don't know who I am anymore I know exactly what we've got in store You're my saviour You're my password How can I write to you When the lines are blurred?
