Charlie Brown cares very deeply for his family and friends, even if he was maltreated by them. His care for his sister is shown on a strip from May 26, 1959(the strip in which his little sister Sally was born), when he exclaims: "A BABY SISTER?! I'M A FATHER! I mean my DAD's a father! I'M a brother! I have a baby sister! I'M a brother!" at her birth, and two strips later threw a celebration over it by handing over chocolate cigars to his friends. When Charlie Brown was maltreated by his companions (most often Lucy, Violet and Patty), he does not usually take out his anger on them, but often retaliates and even manages to turn the tables. An example is a strip from 1951, which features Violet and Patty telling Charlie Brown that they are not going to invite him to their party, with Charlie Brown replying that he does not wish to go their "dumb ol' party" anyway, leading the two girls to invite him.
