McCourt's tale of life as a muddler while leading a classroom offers an interesting contrast; few such dedicated muddlers can manage to arrive on time for 8 am classes. McCourt doesn't deny or justify his muddling, or in any way apologize for it; similarly to Angela's Ashes or 'Tis he lays out the circumstances of his life without obligating the reader emotionally. This lack of obligation instead results in a purer response; when he isn't asking for your sympathy, he earns it.
Strangely enough, muddling through his days as a teacher McCourt gradually finds himself successful as a teacher. Many parts of the story read like they were left over bits from an episode of Welcome Back, Kotter. His story gives hope to all muddlers, that having a good heart and keeping with a job day after day might make one good at it.
