(Strip Number 269, Original Publication Date, 7 June 1982)
Panel 1: As Elly does the dishes, Mike comes up to her and says "Mom! Elizabeth is teasing me! She's looking at me! See? She did it again!" Given that Lizzie looks like she has no eyelids, I can see why Mike would be creeped out by that.
Panel 2: Elly gives the advice one would expect from someone who doesn't really spend too much time near kids: "Don't look at her."
Panel 3: Mike's average-little-kid logic about how even if he does stop looking at her, she'll still be looking at him but he won't be aware of it bores, confuses and angers Elly who rolls her eyes because the offspring-small one isn't making sense on her terms.
Panel 4: Mike's response is to thought-bubble that grown-ups just don't understand how complicated life is.
Summary: Elly will continue to not understand; that's because she doesn't want to see the world through a child's eyes because, well, she has no imagination and can't see that something like being stared at all day long might be considered a problem.
eta: It should be noted that Mike grows up to not see that being seed at is a pain in the neck.
