Personally I might have a high opinion of a singer or novelist or artist, but I don't worship the ground they tread on. I see them as another human being, talented in some ways but probably deeply flawed in other ways.
There's a general tendency to idealise celebrities and put them on a pedestal as if they're somehow far superior to the rest of us.
Even when the celebrity is dead, the worship goes on. There are hundreds of people who dress like Elvis and perform like Elvis. Why oh why?
As for those people deluded enough to think they have a romantic relationship with the celebrity and badger them non-stop with love letters, I feel for the person who's on the receiving end of it all.
Meanwhile Taylor Swift mania has passed me by. What's all the fuss about?
