I'm a frigging ADHD magnet and definitely do not have it myself.
My first and current husbands both have ADD, my second and third bosses were both ADHD, my third boss was as severe as what hyp is describing, noises and all. If he needed something done in a hurry he had a tendency to charge into my office and basically hover behind me, shifting from foot to foot, jingling pocket change. He didn't realize he was doing it, he'd just get caught up in whatever he was currently thinking about and forget where he was and what he was doing. I'd have to shoo him away. He was a very trying person to work for, I had to be his walking memory, anticipating everything he might need to realize he suddenly forgot.
My adult son is extremely ADHD. He's been getting therapy/treatment for it for most of his life and has developed a LOT of coping strategies, but to say he has a talent for pushing people's buttons in the extreme is the understatement of the decade.
