Describe Mr. Braithwaite's first day of school in To Sir, With Love.

bxing match-In gym, Denham insists they have a boxing
class, beginning with him and Thackeray. Thackeray reluctantly agrees. Despite getting
in some early blows, Denham is disabled when Thackeray knocks the wind out of him.
Thackeray draws back his fist to hit Denham again but gains control of his emotions and
declares the fight over. Afterward, Denham waits to speak with Thackeray in the
stairwell. Although Denham admits he was trying to hurt Thackeray in order to convince
him to resign from teaching, Denham is surprised that Thackeray did not capitalize on
his advantage. For his part, Thackeray admits that he lost his temper, but that he
understands the apparent unfairness of some of his decisions. Thackary then offers
Denham a position as a boxing instructor to the younger students next term. Surprised
that he would be regarded as a potential teacher, Denham nevertheless promises to
consider it. Denham is clearly impressed, and expresses his admiration for Thackeray to
his fellow students. By winning Denham over, Thackeray wins back the respect of the rest
of the class, too. He is invited to the class dance, and when he shows up at the Seales
funeral, is greeted by the entire class, who have come to pay their
respects.
