Bio: Patty is often confused with Peppermint Patty. Patty, however, predates Peppermint Patty by several years. She was assumed to be older than Charlie Brown because she attended school at different hours than Charlie, and eventually faded from the strip as Charlie got a little older himself.
Her best friend is Violet, a character who also faded from the strip as time went by.
Notes: Patty is one of the original Peanuts characters, having appeared in the very first strip.
Her propensity to blatantly hit Charlie Brown and to speak fairly directly with other character were defining characteristics generally assumed by Lucy as the years went by.
