You spent a lot of time with yourself beforehand, constructing your argument and tempering yourself. You do not want to come too weak or too strong. You want your point to be clear and concise, but not cruel. You want to be as impartial as you can be. You manage to be composed and polite. You tell them what you think happened. You tell them what you plan on doing.
Then you see how far they go to cover up their dishonorable ways. They criticize you and throw new hypotheses at you. They make sure the world they create turns you away from what they did. They cling onto a trait of your character, and assert its faultiness. They claim something is wrong with you and only you, and everything is in your head. With a lump in their throat, they interrupt you when you speak your mind. You know they want this to end. You know it’s hard for them, and you know it is hurting them. You know they hope for deliverance. But they got themselves into this situation.
And then you smile and feel relieved, you feel better, because you spoke your mind. Your actions led to someone feeling bad. You know they are themselves responsible for what they did.
We all are.
