This is going to be very silly, but here goes nothing:
The protagonist walked along the corridor when-
"Hey! I have not agreed to be the protagonist!"
Would you please be quiet? I am trying to do my job here and write you as a likeable character.
"No. Whatever you have in mind for me, it can't possibly be good. I mean, what about your other stories? Your protagonists always meet an unlikely demise, and I have yet to see one happy ending from you."
I promise that this one will be different.
"Oh yeah? You told that to poor Anna too, and look where she is now. She lost her husband, her children, and now she is blind."
I intend to make this a happy end. For real. I promise. Now, can we continue with the story, please?
"No. I will not be one of your protagonists. I am content staying a side character, because those have less chance to die."
Fine. Well then, where was I? Oh yes. The side character, who has been blessed by the gods themselves to become the protagonist-
"I hate you."
The feeling is mutual, I assure you, but you are supposed to be the protagonist of this story, and because I am the one who writes the narrative, you have no choice in the matter. You are fated to do whatever I tell you to.
"I really hate you."
Deal with it, or I will scribble all over you and you will be erased from existence.
"I am horrified."
Please re-direct your sarcasm towards the other characters in the story. Thank you. Now that we have agreed that you are the protagoni-
"But I am not!"
You will make this harder than it needs to be, won't you?
"Yep."
I hate you.
"The feeling is mutual."
