Idols and Persons

OK, so I've noticed when it comes to 'famous' people, the normal ones are tending to be more ''giving'. Say you're an oridnary person posting a facebook status 'What's up?!', you'll probably receive messages like - 'Meh, nothing". But if you're 'famous' , answers will vary from - 'Nothing much, what about you' , to ' I just sang/played your song / insert title here/.
So why do we act more weird when we have something to do with VIP people? Is it the adrenaline, is it the feeling of talking to someone who has succeeded in their life, or just the opportunity to afterwards tell - I have talked to ... ? "
I personally have talked to Tarja Turunen:


Yeah, beautiful lady, great voice, amazing personality....yet, I felt like talking not to a 'star' but more like normal person with high morals. I guess I have my own opinion of why the guys from Nightwish kicked her out of the band, but yet she's an honest person , deserving to know why she's left out of a band.
So, Tarja was really sweet in our talk, which I'll post this weekeend. She's great person and a professionalist :)
