The other person...

Me, this year !

The other person is always right.

Always right about feelings.
About the day he just experienced.
About the fears (real, unreal or ill-founded) in his life.
About the narrative going on, unspoken, in his head.
About what he likes and what he dislikes.

You'll need to travel to his place of 'right' before you have any chance at all of actual communication.
