Yes, in essence, it is bright, is grand
Yes tells me you understand
Yes allows opportunities
Yes can end uncertainties

Yes confirms that I am free
Yes, confirms you will marry me
Yes says that I give consent
Yes, it allows, while not prevents

Yes, confirms, I will take that job
Yes, affirms the terms that I agree
Yes, makes visible what no one fails to see
Yes, those three little letters are critical.
