I've discussed this series of Peanuts comics before, where Peppermint Patty finds herself face to face with the Little Red Haired Girl, and in an unusual twist for the normally confident Peppermint Patty, she finds herself in tears when she sees in the other girl someone and something that she feels that she can never be. Her feelings of helplessness are deepened, of course, by the fact that The Little Red Haired Girl is the unrequited love of Charlie Brown, who Peppermint Patty not-so-secretly fancies.
Anyway, I found the comics re-imagined as a series of gifs and decided to share a shortened version of them here. (I am not the creator, just a fan. You can see the full version here.)
