However, if you owe something, you will never be able to repay it. For example, you don't want to do things for yourself, you want to do things for your family, but the people who help you do things are just because of your face, and when your family always needs help, there is nothing you can do. You can only ask this person who can help over and over again. The focus is on your "intention", and the other person doesn't care at all. Then this is the "debt of gratitude" you owe. Even if the relationship between two people is no matter how good, you will feel indebted to others.
People must understand human feelings all their lives, because we can't really be "Dont Ask For Help" all our lives. Therefore, as long as we are grateful, even if we can only do our little bit when the other party needs help, we still have to do our part.
