Who's Who?

I was talking to myself just the other day
I was hearin' lots of things I never thought I'd say
But one thing I said really blew my mind!
(Who's who?)
I said: You don't know me, but I know you
And if you listen closely we can talk it through
It ain't as simple as we're gonna find!
(Who's who?)

I think I will save you, I think I don't blame you
'Cause I like you and you like me
I was talking to myself just the other day
Then the bad man came, took me away
I feel bad
But not as bad as me!
(Get off me, man!) I was talking to myself just the other day
(You've got the wrong man!) then the bad man came, took me away
(I am not that man!) I feel bad
But not as bad as me!
