As a son or daughter, you and I can understand that you are better than your mother, but you should know that buying another jewelry box is more valuable and meaningful, but it is still not the original one.
If you are a student, saying something old-fashioned and studying hard is the best thing to repay your parents.
If you have entered the society, you have a wide range of choices.
In short, the past is only suitable for keeping history in your heart. What you have to do is to seize the moment and do something more meaningful to let your mother know that your heart and your mother's future are yours.
