You're in Love, Charlie Brown

Charlie Brown struggles to enjoy himself like his peers as summer approaches, and when he spots the Little Red-Haired Girl on a passing bus, Linus deduces that Charlie Brown is in love. Determined to catch her attention, Charlie Brown makes several unsuccessful attempts, including accidentally reading a love note instead of his report, sharpening his ballpoint pen at the pencil sharpener, and failing to muster the courage to approach her during lunch. His friends, Linus and Peppermint Patty, try to help, but only aggravate the situation. In the end, Charlie Brown discovers a note from the Little Red-Haired Girl that reads "I Like You, Charlie Brown" signed by her, leaving him overjoyed and eagerly anticipating their future together in September.
