Not sure what the dictionary says, but I’d define “rapport” thus:
“Ability and consensus between people to get along; having an affinity, one to the other helps this condition;.”
My three kids and I got together with a good friend and her family the other day after work. My kids and theirs had never met. You wouldn’t know it though from the way they got along. They laughed and played. It was inspiring. They were fast friends. Easy rapport.
There were a few other adult folks who where at this gathering too. I’ve been friends with them in varying degrees these last 50 years. There was a lot of shared history co-mingling that evening. Easy rapport.
So fun to get people who like each other together. So much love is possible when we appreciate and enjoy other people — who they are, how they are, what you have together. Easy rapport.
