If a person tells you something that doesn’t seem right, acknowledge their thought first. That person arrived at that thought/idea/conclusion after some thought processes. While that may be flawed, you can always fill that with your knowledge, process it, and then communicate further by taking some more time (if feasible).
While this entire process isn’t as natural as it might seem, if you start resenting to their viewpoints from the get-go, you’ll end up messing it all. Even if the discussion at hand ends smoothly, the relationship might not.
Avoid resenting or barricading others’ thoughts immediately when it’s being told. You could take a minute, listen to their side of viewpoints, and find out facts that are correct or incorrect and then present yours. This will allow them to first vent out and empty their thought buckets, so you could start filling it again with yours.
Unless this happens, all you pour out will keep overflowing and will never fill their minds. So, avoid resenting viewpoints and go with the flow. Things will be on track and in control eventually if you let the kite fly high while you know the thread is in your hands.
Cheers, and good luck!
