Note to friends: a note is informal and straight to the point
Hey. I know we had plans but there's been a change. I got in trouble a while back and my parents are sure of me going out. I've been trying everything, from doing all of my homework, getting good grades, and even doing extra chores. I will try to convince them to let me hang tonight. Talk to you soon and I'll keep you updated.
Letter to parents: Formal and well-planned
Dear Mom and Dad,
I understand that you may still be upset that I messed up. I am truly sorry and I promise it will never happen again. I am writing this letter to ask you for leniency in your rules. I understand that I must suffer the consequences of my actions, but please consider the fact that I have never been in trouble before. I assure you I have learned from my actions and these things will never happen again. I am asking for a latter curfew hour and more days to spend with my friends. I ask that you think hard about this and consider the facts.
Thank You,
(Your name)
