Tom era indubbiamente l'allievo più intelligente di tutta la scuola, ma ogni volta che l'insegnante gli faceva una domanda per la quale non era preparato, era pieno di tale nervosismo che sarebbe diventato confuso, e qualcosa di assolutamente incomprensibile sarebbe uscito dalla sua bocca non appena la avrebbe aperta.
