I agree with @canidmajor I take offense to being called a commoner in this question? Sadly too, most celebrities are not of the caliber they used to be I am sure you agree? However, I do have a fond memory of Right Said Fred.
I was in my 20s and sitting in a luxury coffee shop of a 5-star hotel. I used to frequent that place with my girlfriend. I was being ‘eyed up’ by a young guy rather overtly. The next moment he was joined by his brother, the then, very popular Right Said Fred.
I was into their music but unlike many others, I still do not know their real names. I just wasn’t that ‘into’ famous people. I could appreciate a song, appreciate an actor but didn’t have to know all about them. I do expect ‘famous’ people to behave a certain way towards their admiring public, or at least just be polite, it bodes them well in the long term.
Just as a side note, and speaking of behaving well. Recently Ewan McGregor left his wife for a younger lady and was asked by a popular departmental store to do their advertising. They have reported back that it was a dismal failure. I reckon ditching his wife has not put him in public favor. Clever celebs’ should work their audience don’t you think?
