I feel the same way.. Don't actually have a super strong opinion on Bezos either way, so reading a lot of the comments here.. They seem painted with loathing for him.
He's just a dude and was caught up for seconds with the party atmosphere while an old man was getting his words together. Yeah it was obvious to everyone watching he left Bill hanging, but he also seemed self conscious about that and came back to him..
Also, I call Bill an "old man" because he is. He's also one of the most present 90 year olds I'm aware of and is incredibly smart and with it. I would feel lucky if I was half as with it at 60-70, much less 90.
