Letter of apology to a friend after a quarrel.
Step-by-step explanation:
ABC Avenue

Dear Shawn, 
I know I have said that I will never talk to you again after our huge fight. But I have also had time to reconsider the situation and gone over it numerous times. And one thing I have realized is that the fight, or for that matter, anything, is not worth ending my friendship with my friend. 
I admit the fight was violent and raw. But through it all, I have ignored the times you have stuck by me even during the worst of times. And for that, I am grateful and also regretful about the fight at the same time. 
So, here is my apology letter, asking you to forgive whatever I had done to you and also to forgive me for all the hurtful things I've said. I have overstepped my boundaries and would like to admit my fault. 
So, please accept my sincerest apology and give me another chance to get your friendship. I will make sure to not do it again and prove my loyalty to our friendship more. 
I am deeply sorry. 
Forgive me. 
I will be awaiting your reply. 
Sincerely. 
Jake.
