Year 1, Chapter 1:
—The boy smirked at him. "Never said you were. Father told me that you were my age, but I had no idea we'd meet before getting to school. I've been looking forward to meeting you. I'm Malfoy, Draco Malfoy."
He held out his hand.
Harry wasn't used to people offering polite greetings. If his uncle and aunt ever had to introduce him, it was dismissively. His cousin had warned other children away from him. The simple gesture gave him a warm feeling of hope. Maybe things wouldn't be so bleak in the wizarding world.
Harry shook Draco Malfoy's hand. "Nice to meet you."
Year 1, Chapter 4:
The last thing Harry saw before the hat dropped over his eyes was the hall full of people craning to get a good look at him. Next second he was looking at the black inside of the hat. He waited.
"Hmm," said a small voice in his hear. "Difficult. Very difficult."
It was to be just like choosing a wand, apparently.
"Plenty of courage, though you don't believe it. Not a bad mind either. There's talent, oh my goodness, yes, and a nice thirst to prove yourself. Now that's interesting. So where shall I put you?"
Harry was thinking about the new friends he'd made, children who had opened their arms and hearts to him. They didn't treat him like some freak show the way the people in the Leaky Cauldron or the Granger bint had. They were a bit rough around the edges, but they treated Harry a sight better than anyone ever had before. He really didn't want to go to a different house from them.
"Already made friends in Slytherin I see, yes, and you want to be with your friends. You could be great, yes, and Slytherin would help you on your way. It seems to me that everything points to SLYTHERIN!"
