(Strip Number 4526, Original Publication Date, 1 November 1985)
Panel 1: After the dance, we find ourselves at Casa Foob. As Mike walks into the house, John asks him how the party was only to be told it was okay.
Panel 2: When John asks if there were a lot of costumes, if he played games and if it was fun, Mike answers him with a non-committal "I guess."
Panel 3: Since John is unaware of the need children have not to tell parents too much, he's baffled by Mike's insistence that no, there isn't anything to tell about the dance.
Panel 4: Mike's gleeful thought-bubbling about how Deanna kissed and made up tells us that there's nothing Mike is willing to tell him.
Summary: This, I think, answers the question of why Michael doesn't avail himself of the advice of adults or ask them for help: he's a firm believer in the playground code of honour that states that talking to a grown-up makes him a dirty snitch who'd sell out his friends. Also, why talk to a man who's proven himself able to twist anything you do into something bad. If he'd said he had a good time, John would have found a way to make him into an out-of-control monster whose attitude needs adjusting.
