Looks unhappy, coz he just lost the single match, and he walked alone, i came to him asked for the pic, he said ok, but, u c, he was really really sad.
After his doubles match, he won, and i was sitting with his ABC (America born Chinese) friend, he took the pic for us.
I said, Hey Bjorn, i took a pic with you this afternoon, but you was so sad, u didnt smile. can i have one that with your big smile on your faces?
then his friends laughed loudly, he was shy, and we had this pic
