Siblings
A sibling is one of two or more individuals having one or both parents in common. A male sibling is called a brother, and a female sibling is called a sister. In most societies throughout the world, siblings usually grow up together, facilitating the development of strong emotional bonds such as love, hostility or thoughtfulness. The emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family.
