Being very close to a sister can also lead an individual to prioritise a biological bond over other nourishing friendships. From young adulthood onwards, friendships positively influence self-worth, social acceptance and adaptability. Healthy young adults tend to have a network of social supports that comprises close connections with friends as well as family members. Dense family networks, or people who focus primarily on family, are found to have less contact with non-family, and this reduced variety in their network can make them more vulnerable if family bonds suffer or break.
