I'll write to you Penpal.

Charlie Brown and the little red-haired girl from Peanuts.

Written and illustrated by Charles M. Schulz, The strip focuses entirely on a miniature society of young children, with no shown adult characters.

The main character, Charlie Brown, is meek, nervous, and lacks self-confidence. He is unable to fly a kite, win a baseball game, or kick a football.

The Little Red-Haired Girl is an unseen character in the comic strip, who serves as the object of Charlie Brown's affection. While never seen in the strip, she appears onscreen in several television specials. The  2015 film marked the first time the Little Red-Haired Girl spoke in all Peanuts-related media, with Charlie Brown finally succeeding in talking to her.
