(Strip Number 587, Original Publication Date, 5 April 1984)
Panel 1: As Elly puts some artwork together, Mike asks her "It's gonna be my birthday soon, isn't it?" She says yes, it is.
Panel 2: He then says that he's been invitin'guys over to his party and asks how many he should ask.
Panel 3: She reminds him that he KNOWS that since he's turning nine, he can only invite nine; inviting one guest per year old is what the Pattersons do, after all.
Panel 4: Since her response to his asking her if he can have his fifteenth birthday early is to get all gobsmacked, it looks as if not understanding how kids think is what Elly does.
Summary: We can probably expect this to be accompanied by notes saying that this is a) something either she or Aaron tried to pull and b) confused the Hell out of at least one adult. What we won't get is an admission that she skimmed through the relevant article and cherry-picked the parts that pleased her.
