From: Harry Potter and the Prisoner of Azkaban, Chapter Nine, "Grim Defeat", p.188. Harry first learns his parents' last words in the Prisoner of Azkaban during his series of Dementor encounters.

In the Harry Potter series, the broom has a more practical function: every witch and wizard must learn to transport themselves using a broom. Meaning: a period of working time that is late at night.
