"Well, well, if it isn't my two favourite men," Draco said as he and Violet approached them. "You can go in a minute." Draco inspected the robes, and smoothed out the wrinkles with his wand.
"You always need to look impeccable when making a grand entrance. You keep your wand arm free, and offer the lovely ladies your other arm, just like this," he explained. "Go on, do it. Violet, dear, you just touch his arm, not use it to drag him around. You walk out, head high and look at people straight in the eyes. Never back down, and no running, shouting, climbing. Try to behave like purebloods. Now, you may go."
Draco watched them walk away, smiling. "How long do you think it'll last? Five minutes? Ten? And to think that I would have never disobey my father. I was the proper child all through the night." He turned to Severus and grinned. "And don't you look gorgeous. I made my own grand entrance with Tracey, but I thought it'd be fun to make one with you as well."
