Dear Mom,
I hope this note finds you well.
I wanted to take a moment to apologize for not helping you with the house chores yesterday.
I know you must have been very exhausted after a long day at work, and it was unfair of me to leave all the cleaning tasks to you.
I should have offered to help and lighten your load.
I want to assure you that it was not my intention to neglect my responsibilities.
I realize that keeping our home clean and tidy is everyone's responsibility, and I should have done my part.
I promise to be more mindful and proactive in the future, and make sure that I am doing my fair share of the work.
Once again, I am deeply sorry for any inconvenience or frustration that I may have caused you.
Please let me know if there is anything I can do to make up for it.
Love,
[Your Name]
