Most siblings argue and quarrel occasionally.
They fight over possessions, space on the sofa, time in the bathroom, or the last donut. On most days, though, siblings are friends and companions instead of rivals and competitors. The ambivalence between love and hate is present in all close relationships. This ambivalence becomes more intense in siblings because both want to gain their parents' attention and be their parents' favorite. The positive side of sibling rivalry is that it gives children a chance to learn to give and take, share, and stand up for their rights.
