At the beginning, he showed us a smiling face. Looks pretty strange to me.
He soon became so serious and I like this much better especially when he is talking something serious.
His ties is "slightly" different from the one he was wearing for Friday's show. Also his hair is longer than now.
P.S. Thank you for all of your comments and email messages. Sorry I haven't had enough time to reply to them all. (But I updated this blog so that everyone can know I am OK.) Anyway, I'll definitely write you back soon!
