You push him back

While your brother might have been stronger than you, you were no push over.

Angered by his insinuations and name-calling, you push him back, causing him to fall down on his ass. You are about to lunge at him when your father finally stepped in and broke the fight.

"Boys," your father interjected, diffusing the situation, "Calm the fuck down."

He pulled Aaron back up and tried to placate him, "We all knew that the risks were there, Aaron. You could never predict what class you'd get. You have to accept the cards that you've been dealt. You know that."

"B-but", argued Aaron as he tried to hold back his tears.

"Enough," roared your father, "I did not raise you to be as whiny as this. You need to accept your fate. Man up, Aaron."

"Yes, father," agreed Aaron, lowering his head in shame before saying something that he would soon regret, "It's just so unfair that my faggot twin is the one who-"

In a surprising turn of events, your father backhanded your brother while he was mid-sentence and sent him reeling back down to the floor.

"Don't you fucking insult your brother like that ever again," he shouted at Aaron, his body shaking in anger, "Go to your room. I'll deal with you later."
