Charlie Brown is first seen interacting with the character Lucy van Pelt on March 3, 1952. He was on better terms with her at first than later in the strip, as they often made fun of each other out of mere playfulness. The November 16, 1952 strip is the first strip in which Charlie Brown was prevented by Lucy from kicking a football; in this strip, she pulls it away because she fears that Charlie Brown will get her new football dirty, and then on the same strip, she holds it too tightly, so Charlie Brown is unable to kick it for a second time. Charlie Brown first began flying a kite on April 25, 1952 strip. Charlie Brown is first seen with Linus van Pelt on the September 19, 1952 strip. Charlie Brown was unable to talk to him because he was introduced as an infant. Similar to Schroeder, Linus caught up to Charlie Brown in age and settled as being slightly younger than him; on January 18, 1956, Linus befriended Charlie Brown, and eventually he would become Charlie Brown’s best friend, and their current relationship was established.
