It is on this point that our opinions differ.

But I will always be honest with you about the challenges we face. I will listen to you, especially when we disagree. And above all, I will ask you to join in the work of remaking this nation, the only way it's been done in America for 221 years; block by block, brick by brick, calloused hand by calloused hand.

Every opinion is a mixture of truth and mistakes.

You may be right, but I am against your opinion.

I'm afraid I differ with you on this point.
