Every person and every people on the whole Planet Earth have at least those bad, good, vengefullness, sad, and e.tc memory. But be glad that you have them because you could learn from those mistakes and make life easier. I hear around me everywhere saying life is not fair. Yes, I do agree that it's not fair. But look life is never fair to anyone. So just live your life and have smile on even though you have those good and bad days.
