For as long as Harry could remember, he knew his name as Freak. During his primary days, he would only respond to the word freak, and nothing else, he didn’t say much, but when he did, he said one word, “Apathy.”
This trend ostracized from everybody at Hogwarts, that was until fourth year, when he met someone with blue eyes and blond hair, she asked for a dish he couldn’t name, and then she asked for his name. His response: “I am nobody, who are you? Are you nobody too?”
