Give me time and your attention so that we can talk, really talk. Don't assume based on my opening sentences you understand what I'm saying or the perspective I'm approaching it on. Ask questions, repeat back to me in your own words what you think I'm saying, and give me the opportunity to clarify and correct. I will also do the same for you.
I have this problem all the time. Most people don't have patience with this, so they get defensive, sometimes in an offensive way.
