Someone can tolerate you, not because someone owes you, but because they care about you very much; someone can forgive you, not because you admit your mistake, but because they are afraid of losing you. If you are serious about a person, you will be wholehearted; if you are persistent in a relationship, you will stick to it to the end. I use all my strength just to understand you; I spend time and energy just to wish you a happy life.
