one day to do over

If you had one day to do over what day would it be or would you not redo a day over? If I had one day to do over it would be one day when I was in 6th grade. The reason I would do it over is because I said somethings that I should not have to my parents. My parents did forgave me but it take along time. That is the day I would do over what day would it be for you.
