Interesting read.
Hate it when articles like this make me second guess my childhood adoration.
I wouldn't second guess too much. I've been lucky enough to associate with many of my heroes and often in situations where they were 'normal' people as opposed to meeting fan situations.
One of those was being lucky enough to attend a BBQ and spend the night at Greg Norman's house. Like most superstar people he has an air of confidence and an aura about him, but equally like most of them he is a decent and friendly guy. Absolutely he likes talking about himself and the way he looks, but any of us would have a beer and a chat with him and come away thinking he was a top bloke.
One tip I'd give is never judge someone by someone else telling you about a time they met them and the person was rude etc like the interviewer mentioned early in that article.
Everyone famous has someone who will tell you about the time they talked to them or asked for a photo and got a brush off and how that makes them an *smile*. In my experience, having stood and watched that scenario many, many times it is almost always a case of being reflected back what you give. People are rude and demanding and wonder why they get a no. I've had people tell me about the time they met Shane Warne and what a prick he was and yet I know Warne signed and took photos with almost anyone who approached him respectfully.
Everyone has moments when they have had enough and it's one request too many but again in my experience the famous person tends to do it politely and cop the outrage and rudeness from the person they deny. People just don't understand how horribly they come across sometimes.
