Each of us was a newborn baby. But we are not the same standing. What could say babies?
Maybe children is that God sends angels to people. When these angels is born, they tell us about a paradise, about other angels. Sometimes, when his parents quarreling, this little angel wants to calm and to reconcile them. He cries when it fails.
Pity, but with time we destroy angels in children. They learn to be angry, deceiving like us.
