Ummm i'm not sure about the question because you didn't give a story. Sorry I know this isn't an answer
For 1)put a comma after the word homework.
I would say it is important to distinguish fact from opinion in an essay because C. essays, particularly formal ones, persuade or inform the audience on a topic, thus requiring details that can be proven.
You need to use real facts if you want to persuade somebody into believing you, not just to present your own thoughts and opinions.
Dear Dad,
This is my apology for driving your car out with out permission. I understand that not asking was wrong of me and I give you my word I will do better. I'm truly grateful for all you do for me and I'm sorry to mistreat you and your trust the way I did. I genuinely hope you can forgive me for my poor choices and bad actions. I am not even aware what I would do without you. I love you very much and I'm SO sorry.
Love
(enter your name),
