In communication, you are responsible for 100% of your 50% of the conversation.
So is the other person.
That means that if you only communicating half as well as you could, then the entire conversation going to be very poor, because it’s largely incomplete or worse.
So, when the other person is frustrating you, or not listening, or being closed off, just remember: you can only control what you can control.
The rest is up to them.
It’s up to you, first, to bring your side up to 100%.
Sometimes, that’s the only way to move forward.
