Why do humans need to have friends?

Having friends may seem simple to many; however, making friends might seem pointless for some. Have someone who will be there for you and reassure humans. Many might say they do not need a friend since they have a significant other; however, your significant other should always be your friend. A friend is always there for you, will not judge you, and will always tell you what you are doing wrong. And it is necessary for someone to have someone like that.
