According to Psychological Today, “Psychologists are discovering that human beings have a fundamental need for inclusion in group life and close relationships. » Without the people others need for fundamental reasons, the effects can change them as a person. In Of Mice and Men, the two main characters, George and Lennie, work on a new ranch. They meet new people and try not to get into trouble. However, not everyone is part of the group. Some are left behind and may feel alone. George and Lennie, meanwhile, have a compelling friendship. In The Fault in Our Stars, Hazel, a girl with cancer, was touched by the one and only Augustus Waters. They both suffer from cancer and end up falling in love with each other. They go on a trip to Amsterdam and meet Peter Van Houten, who is feeling a little lonely. Throughout the novel, they find themselves at their strongest and weakest points in life and need each other to get through it. Of Mice and Men and The Fault in Our Stars are similar in the way they demonstrate themes such as the negative effects of loneliness and the value of friendship. Of Mice and Men and The Fault in Our Stars are very similar in their themes. One of the common themes they demonstrate is the negative effects of loneliness. Crooks, from Of Mice and Men, is a black man. His race made him feel alone because no one was going to be friends with a crippled black man and everyone judged him for who they think he is. Crooks reflects on the importance of having someone around and what loneliness does to a person: "A guy sitting here alone sits here alone at night, maybe reading books or thinking or stuff like that. Sometimes he thinks, and he has nothing to tell him what is right and what is wrong... middle of paper... or George and Augustus care about Hazel. George takes care of Lennie and Hazel takes care of Augustus. Of Mice and Men and The Fault in Our Stars are similar in the way they demonstrate themes such as the negative effects of loneliness and the value of friendship. In both books, the effects of loneliness led Crooks and Peter Van Houten to not know what happened and to become alcoholics. Another theme that both books represent includes how much each character loves each other to form a strong and lasting friendship. Whether it's handing out ketchup or taking an international plane, the friendship between the characters cannot be avoided. Overall, being alone is no fun, and having a close relationship is how you will become happy. Remember, if people are lonely, become their friends. Feeling alone and having a friendship could have a complete impact on that person's life.
