 Don't ever say to anybody, you're wrong. Don't do it. Wipe those two words out of your vocabulary. The minute you say those two words to anyone, the conversation's over, you've kicked in their fight or flight response, and you'll no longer have a chance. The other thing is, think about how you choose your words. Here's a tip I give to the college kids. Don't say to somebody, I disagree with you. Say to them, I see that differently.
