Apologies are pretty straightforward with three key components:
- Take responsibility for your actions/ the situation
- Express regret
- Request forgiveness & assure will not happen again/ you will attempt to prevent a recurrence
Dear Person I Have Wronged,
I am sorry I (hurt your feelings/ broke your object/ what did you do which requires an apology?). I did not mean to do it. In the future, I will (consider your point of view/ look where I'm going/ not do it again/ etc.). I hope you can forgive me.
Sincerely,
Signature
The important part is to be sincere and actually mean what you're saying when you apologize. I hope this helps.
Just a thought....
