“Is it true?" he said. "They're saying all down the train that Harry Potter's in this compartment. So it's you, is it?"
"Yes," said Harry. He was looking at the other boys. Both of were thickset and looked like bodyguards.
"Oh, this is Crabbe and this is Goyle," said the pale boy carelssly, noticing where Harry was looking. "And my name's Malfoy, Draco Malfoy."
Ron gave a slight cough, which might have been hiding a snigger. Draco Malfoy looked at him.
"Think my name's funny, do you? No need to ask who you are. My father told me all the Weasleys have red hair, freckles, and more children than they can afford."
He turned back to Harry. "You'll soon find out some wizarding families are much better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there.”
