Write them if you need to

All this is about...

If he asks you not to do something: Then don't do it.
He will explain if you don't understand.
Other people were trying to help you understand.
People tend to be most forgiving when they think you understand why
Because they think you will be less likely to be doing it again.

'Sorry' means 'I understand I did something wrong and I'll do my best not to do that again'.
If you don't mean the latter half then you aren't really sorry.
If you are really sorry then I'll think you'll find people are fairly forgiving.

But you do need to stop making the situation worse.
