Make Everyone Happy/mechanical Birds

And I said you shouldn't make facts out of opinions
He said that I was right
You're right I knew that I was
And I'd hate to see anybody thank you
But I'd like to see you fail saying thank you though

I'm not sure who I am but I know who I've been
And I said you can't make everybody happy
He said you'd like to at least make yourself happy though
I'm not sure who I am
I'm not sure who I am but I know who I've been
