(Strip Number 323, Original Publication Date, 22 October 1982)
Panel 1: As she, Elly and Lizzie go for a walk outside, Anne tells Christopher to help her push the baby carriage; his response is to say that he no want to push, he want to ride.
Panel 2: Her telling him that there's no room is greeted by his yelling YOWL!!!!!
Panel 3: As she carries Richard and pushes a big, stupid, jealous idiot in a pram as he grins about making an ugly fool of himself, Anne tells Elly that she didn't think that sibling rivarly began this early.
Summary: It's sort of obvious why we always see small children thinking that parents love a younger child better than they do; they're all a stupid, selfish, malicious little girl named Lynn Ridgway whose ignorance, default hostility and insane defiant streak confuse the need parents have to protect the helpless with not only favoring younger brothers but with willfully ignoring her and hating her.
ETA: They've altered the home-page again; instead of buttons with character's faces on time, the menu options in the banner are more standard-looking tabs of varying web colors. Also, the banner on the home-page is a seasonally-appropriate image. The first is one in which Elly tries to foreshadow Andy Fox.
