Draco raised an eyebrow. "Since when? People can wait to have the honour to see me, and their needs are always subservient to mine. I believe you thought me that."
He smiled at his father. "You know you're always been welcomed here... just not officially. One must keep up appearances, couldn't possible have the enemies of wizarding Britain waltzing in and out, could we? Do point that out to aunt Bella. Next time, she might think twice of just pushing through the wards, or trying to." He had to thank Severus for making sure that old and new were intertwined together so no one could get him.
"I'm happy, Father. Tracey is a wonderful wife and friend." He didn't mention that she understood that he had a lover on the side, plus random shags. "Now, care to sit? Would you like anything before you tell me why you're here?" He didn't think for a moment that this was a social visit.
