(Strip Number 959, Original Publication Date, 15 October 1985)
Panel 1: We start things off with Elly telling Mike to hand a note to Principal Warren.
Panel 2: When she tells him that said note is all about how she's volunteered to chaperone the Halloween dance, a horrified Michael asks why.
Panel 3: Elly reminds him that his teachers put up with his behaviour every day of the week; the fact that this is the case still doesn't make him understand why so he asks her to make herself clear.
Panel 4: She walks off and tells him that she owes them one.
Summary: Elly and her kind think that Mike's antics exist in a vacuum so believe this to be an example of poor Elly having to make things right with the teachers for the acting up that she has nothing to do with. What they lose sight of is that if a child misbehaves, it's a sign that the parents are somehow delinquent and must make amends for their failings.
