- Dudley Dursley mocks Harry Potter

Harry Potter's twelfth birthday was wildly ignored by his uncle, aunt, and cousin. Although Dudley did remember his birthday and mocked him for it. Later, on his birthday, Dobby the House-Elf arrived and warned Harry not to come back to Hogwarts School of Witchcraft and Wizardry, ending with throwing Petunia's cake onto Mrs. Mason's head.
