"Draco, there's sand in my shoes!" Pansy whined.
"You didn't have to come here. Go back home," he retorted icily.
Pansy sped up so that she could keep up with him.
"Why do you come here all the time? It's boring… There aren't any shops!"
Draco sped up so that he wouldn't have to listen to her irritating voice directly in his ear. He didn't care about shops or getting sand anywhere… he remembered a night two years previously when he had had plenty of this same sand in... interesting places.
"I came here to be alone."
Pansy stopped trying to keep up with him, and left in a huff. Headed for Diagon Alley, no doubt. He let out a sigh of relief, and proceeded to the rock where he had first met Luna.
