I Do Not Want to Fight

I didn’t know about the “Gaslighting Effect” until I read the book “The era of post-truth.”
It is a form of psychological abuse. I realized one of my friends was a victim of it.
The issue that was (3)canvassed is still unresolved.
Nobody imagines that the lover who (1)caresses your cheek is trying to deceive you.
I can not be (4)on the ball if somebody has some malicious intent. How can you manage and (2)cease it? I know the famous quote by Sun Tzu. However, I do not want to fight. I want to know how to avoid the fight.

Title: I do not want to fight.
I didn’t know the word “Gaslighting Effect” until I’ve read the book “The era of post-truth.”
The word meaning is a psychological abuse. I realized one of my friends was a victim like this.
The issue that was (3)canvassed is still unresolved.
Nobody imagines that the lover who (1)caressed your cheek, he or she trying to deceive you.
I can not (4)on the ball to head if somebody has malice and attack. How can you manage and try to (2)cease it? I knew the famous quote by Sun Tzu. However, I do not want to fight. I want to know how to avoid the fight.

“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
― Sun Tzu, The Art of War

homework: (1)cease, (2)caress, (3)canvass
Expression: (4)on the ball.

If you are on the ball, you are aware of what is happening and are
able to deal with things quickly and intelligently.
We need someone who is really on the ball to head the fund-raising campaign.
