I can see how a personality as intense and as driven as Cobb by all accounts was, would alienate a lot of people, perhaps inadvertently. It is really hard to turn off the focused aggression. You can't do it on a dime, you need to decompress. I know that from personal experience as a litigator. The secretaries at one firm used to call me "the meanest man in the office" because I was so offensive when I was 'on', and it would carry over into my interactions with them. Took me years, and a few HR complaints, to get it under control. I can see that happening with Cobb. He probably needed some down time to decompress that he did not get before having to deal with others. And weed. Works for me
