When you are growing old, you will see different perspectives of a single coin. When we were young, we saw it as a coin which has two sides. It conceives with our mind, we thought it's normal ... dark and light, evil and good.
We all wants to be happy, even if it's only a slightest piece. In a life of every man, we were born, enjoyed playful children's period, went to schools, universities. We fall in love, we got married. We got ourselves an image of both of us, we watch him grow. We fight with each others, we argue, and we get old then we stop fighting, we take care of each other more.
