He screamed a lot if you made a mistake. He swore like a sailor. He threw things such as his cell phone at men (never at women, although I was sure he wanted to) when he thought they were stupid beyond his reasonable expectations. Over the years I learned how to duck quite vigorously to avoid flying cell phones, pens, staplers and such. He didn’t care what people thought about him. He knew that some of us were deadly afraid of him, and said to me once that fear, in his opinion, equals respect.
