Zacharias had been sipping at his Firewhiskey as he waited. Licks of hot smoke and alcohol slipped down his throat, creating that pleasant burn that he was well used to by now - oh, he didn't choke on it, not like he did the first time he snuck some when he was much younger.
At the knock, his gaze flickered up, and he watched as the door opened, and Draco entered. Zacharias dipped his head in a nod of greeting. "Hello, Draco," he said, rising to his feet to offer his hand to shake in an amicable and polite manner. Returning to his seat only when the handshake was finished.
