You can't tell me what to do anymore Cos I'm free as a bird and I'm glad to be Who I want to be. Cos I've been under the thumb for too long With youtelling me I've got it worng again, And you can't pretend. But I don't care what you 're thinking at all, Stop trying to make me feel small, Cos I think you're a big know-it-all. Look here darling, I'll never be you Cos it's crazy for there to be two of us - Isn't one enough? But you keep trying to take over And I'm not going to surrender, Cos you've got some gall And I think you're a big know-it-all. You can't tell me what to do anymore Cos I'm free as a bird And I'm glad to be Who I want to be. Cos I've been talking it over And now I'm looking for closure Cos it's no ball When you live with a big know-it-all. And I think you're a big know-it-all.
