Peppermint Patty is a tomboy who is forthright, loyal, and has what Schulz described as a "devastating singleness of purpose". She frequently misunderstands things, to the extent that it serves as the premise of many individual strips and stories; in one story she prepares for a "skating" competition, only to learn with disastrous results that it is for roller skating and not ice skating. She struggles at school and with her homework, and often falls asleep in school. The wife of Charles Schulz, Jean Schulz, suggested that this is the consequence of how Peppermint Patty's single father works late; she stays awake at night waiting for him. In general, Charles Schulz imagined that some of her problems were from having an absent mother.
