"Andy was polite and humble. He rarely told anyone to do things— he’d just ask in a hopeful tone, “Do you think you could … ?” He treated everyone with respect, he never talked down to anyone. And he made everyone feel important, soliciting their opinions and probing with questions about their own lives. He expected everyone who worked for him to do their job, but he was nonetheless grateful when they did— he knew that any degree of conscientiousness was hard to find, even when you paid for it. And he was especially grateful for even the smallest extra thing you might do for him. I never heard anyone say “Thank you” more than Andy, and from his tone, you always felt he meant it. “Thank you” were the last words he ever said to me."
