To the Boy I met in Madam Malkin's Robes for All Occasions:
Hello,
I don't know if my owl will be able to deliver this letter or not since I don't actually know a name or address to give her, but I thought I would try anyway.
We met in Madam Malkin's on July 31st. I was the boy with the dark hair and glasses. If you don't remember me I won't be offended. We didn't speak for very long.
I'm only writing because I don't know many magical children. In fact, you're the only other one I remember meeting. If my owl is able to deliver this letter, would you write back? I'd like to know another first year when we start school.
Sincerely,
Harry Potter
"Draco, get that owl off the dinner table. Who has sent you a letter?" Lucius Malfoy asked his son.
Draco had been surprised to see the unusual address on the letter the unfamiliar owl had brought him but his expression quickly shifted to disbelief as he saw the rest of the missive's contents. His father was displeased that his question had been ignored. Hoping to avoid an argument, Narcissa Malfoy spoke up quickly.
"Darling, answer your father. Which of your friends has written to you?" she asked gently.
Draco finally looked up, his eyes wide. "He says he's Harry Potter."
