Try it and see what happens. Honestly share your feelings instead of pointing your finger. See if you don't get what you want (understanding) more readily.
Son and I had a long follow-up conversation on why people are so reluctant to do this. Are people unaware of their feelings? Unwilling to share them? Uncomfortable with them? Our mini-experiment convinced me that being brave enough to say how you feel may very well soften others, break down walls, and make for better relationships. Take a chance. Be honest.
