I agree that it must be a very strange situation to be in, going from being a normal (albeit very talented!) guy to having people waiting at the airport to have photos with you, when you least expect it, like in Hong Kong (god, I would hate it if someone wanted photos of me the minute I hopped off a plane!)
Meeting him in Sydney was a surreal experience- he honestly came off as such a normal person that it was difficult to believe this was the same person I had stared at for hours on youtube. I think he has one persona (hopefully his normal one!) when he is hanging out friends (or fans!) and another when he is on stage performing. He puts such energy into his shows that it would unnatural to think he jumped around like that all day in real life.
I think that it is fantastic that he has family travelling with him wherever he goes (what a great job- can I apply!) and obviously gives him a sense of home/belonging no matter where he is.
Let's hope that Mika's star will continue to rise at astronomical rates and his need to do constant (repetitive) press interviews will subside and be replaced with fun, unusual pieces that all his fans can enjoy.
(wow, I think this is one of the first serious threads I have ever posted!!)
