"a boy and a girl were playing together, the boy had a collection of marbles.. and the girl had some sweets with her. the boy told the girl that "he will give her all his marbles in exchange for her sweets." the girl agreed; the boy kept the biggest and the most beautifull marble aside; and gave the rest to the girl but the girl gave him all her sweets as she had promised. that night, the girl slept peacefully, but the boy couldnt sleep as he kept wondering if the girl had hidden some sweets from him the way he had hidden his best marble.. (morale of the story: if you dont give your 100% in a relationship, you'll always keep doubting; if the other person has given his/her 100%). give your 100% to everything you do and sleep peacefully.
