(143 words) It seems to me that kindness means an affectionate and caring, friendly attitude towards people, animals, and the entire surrounding world. This is mercy, a willingness to support and come to the rescue, to take responsibility for someone's fate.
During the war, the hero of the text Anatoly Pristavkin stayed with his sister away from home. Every day he showed little Lyuda photographs of her mother, father, aunt so that she would not forget her relatives. But most of all, the girl was happy to see her brother’s face in the pictures. In the end, only he stayed with Lyudochka: his mother and father died, the aunt refused to take the children. Therefore, the hero showed his sister their common photographs and consoled: “After all, there are a lot of us, right?”
A similar situation is described in the work of A. Rybakov “Children of the Arbat”. After the death of her parents, Nina Ivanova devoted her life to raising her sister. She tried to work hard so that Varia did not need anything, and taught her many useful lessons.
Thus, kindness is a wonderful feeling that unites hearts.
An example from life. When the neighboring girl Olya was left completely alone (her mother was deprived of parental rights), her half-sister unexpectedly was found and took custody of the child. Now Olya and Julia study together, walk, play. This is a truly kind and selfless act.
An example from the movie. The hero of Sergei Bondarchuk’s film “The Fate of a Man”, having lost all his relatives in the war, found a new friend and named son - an orphan boy named Vanya. Andrei Sokolov tells the boy that he is his father, and thereby opens a new page of life for both of them.
An example from the media. Recently, I read in a newspaper about a mother heroine who raised 5 relatives and 5 adoptive children. This is an example of sincere kindness, mercy, compassion for those who are unlucky to be born in a loving family. All these people will grow up, knowing the kindness and comfort of their home, and all thanks to the kindness of this strong woman.
