Bill is a local lad, as is Paul Allen. They me Balmer at Harvard - not sure where he is from. Point is, we have grown up with the MS presence all around us. I have actually been at a couple parties with Bill, before he became Mr Gates.
There are many local stories of eccentricities (all true). For example, he will drive around the block in downtown Seattle several times looking for a free parking space, rather than pulling into a pay garage. When you go to his house, or he sends out for pizza, you end up getting one piece.
Bill has been interviewed (locally) so many times over the years, it is almost like we all know him. But, there was one hour-long show/interview/documentary type of deal where 'in a flash', he revealed much about himself.
The show was kind of a biography of him, and the founding of Microsoft. It was really pretty interesting. Bill was very personable, comfortable and charming during the whole affair. The interviewer said, "I was told that if you were selling hotdogs in the park, soon you would own every hotdog stand". Bill smiled at the compliment and said something humbly appropriate. Then the guy said, "I also heard that when negotiating business with you, it is more like being in a knife-fight".
Bill, completely lost his composure. You could plainly see he was shaken and furious. He was at a loss for words. The interviewer quickly realized he crossed the line and changed the subject. It took Bill awhile to get it back together. I think Bill showed he definitely has a nasty side to him.
