You're in Love, Charlie Brown

It is late spring and school is about to let out for summer vacation, but Charlie Brown is upset about everything, mostly due to feeling disliked and ostracized by his schoolmates. On the way to school, he meets Linus van Pelt and tells him he is frustrated that he cannot enjoy himself like all the other kids at school. But when he notices the Little Red-Haired Girl sitting on a passing bus, Linus immediately realizes that Charlie Brown is in love. Sally Brown does appear and is in love with Linus as usual.
