For proof of Charlie Brown’s acceptance of himself as an undeniable failure face…here you go. Life may get better for him, but not by that much, and not for too long, and it was probably an accident anyway.
(Slight issue I have here. Patty and Chuck are chatting at the neighborhood wall, then at the last square, the wall is gone. Did they start walking away, then Charlie Brown suddenly thought, hey, I got the perfect person for you to talk to right here? I kinda wish Schulz had made this a Sunday, with that exact scenario playing out.)
