Most of the time, work and play get confused. People mistake work for play and play for work. I'm tired of hearing about that one damn incident where Bono (allegedly) turned up drunk for a meeting. It's not right and surely not the behaviour you expect from someone you're having an important meeting with, but I've experienced much much worse situations with people who still kept their jobs (though I wished they wouldn't). Not to apologize for Bono, but I'm sure the whole Spiderman thing didn't go downhill because he turned up drunk for one meeting one single night. And I'm sure he regrets it, we all make mistakes.
The current "hairstyle" is one of these mistakes, btw.
