Dear [Mother's Name],

I wanted to reach out and apologize for the mistake I made earlier today. I mistakenly referred to you as "sir" instead of "ma'am". I understand that this was a mistake and I want to assure you that it was not intentional.

I know that this may have caused you some discomfort and I want to apologize for any offense or disrespect I may have caused. I value our relationship and I want to make sure that we can continue to communicate in a respectful and professional manner.

Please know that I will make sure to be more mindful of my language in the future and I will make sure to address you with the respect and dignity that you deserve.

Once again, I apologize for my mistake and I hope that you can forgive me.

Sincerely, [Your Name]
