Blaise chuckled again. "I'll remind you you said that the next time you're cursing me up and down for my harebrained ideas that cause nothing but trouble," he drawled, teasing.
"What, can't I come and watch?" Blaise mock-complained, but he took Draco's proffered hand and stood, bumping his shoulder into Draco's companionably. "Take all my fun away, why don't you." His whine was the normal one, banter and complaints that didn't really mean anything but affection in guy speak.
"Have fun, mate. Don't do anything that I wouldn't do," he said with a definite smirk. He paused in the door and turned, a wicked glint in his eyes. "Oh, and be prompt, or her daddy might get angry if you make his little girl cry," he said, putting the you-might-meet-the-parents bug in Draco's ear and slipping out before Draco could get retribution.
