Telling people what I think they want to hear makes me crazy.
Sharing my feelings honestly yet sensitively makes me happy.
"Oh friend, I don't want to criticize you! I just worry that..."
"I'm sad that _____. But I love you and will be interested in and supportive of what you love."
This is so much better than trying to agree with people and make them happy when really, I don't agree with them at all!
