Ha... you sound just like me. I will walk into a crowded room and immediately head for the corner or a wall! My normal personality is so very different to my stage demeanor... anyway, I struggle with noisy environments as well, not in the same way as you, but because I get distracted by conversations and other interesting bits of noise. I find it hard to focus on a general group conversation. One on one is no problem....

Anyway, Bangkok... that is a touch futher than Poland this year! Good luck with the contest!
