There were ~ 50 of us and we went to the assigned section. We all asked the guard if we would get to meet Nathan. He said everybody wanted to meet Nathan but he is not scheduled to join the ice break session here. Half an hour later, I wasn't even paying attention. The guard suddenly walked towards me and said I thought you wanted to meet Nathan; look who is here. It was Nathan

I leaped from my seat, shook his hand and started to ramble
I can only recall that I congratulated him on winning the Worlds. Told him a bunch of us got up at 5AM to watch the FS live. He smiled and said thank you. I then told him he is great role model for kids and young people. Then I saw his Yale sweatshirt, and congratulated him on that. Then we took a picture together. He was smiling the whole time. Said a lot of thank you
Then the group started to line up. He took pictures with everyone and signed their posters. Very gentle, humble, and patient. I still can't believe I actually met him.
