From the student's recollection, which the Obama campaign circulated in a tweet:
The moment I will never forget was when he looked at me. He gave me a chance to talk to him. It was like he was waiting for me to say something. I took the moment and signed “I am proud of you,” and his response was “Thank u” in sign language back! Oh my gosh! I was like wow! He understood me after I said I was proud of him. It was so amazing…I was just speechless. Right after he thanked me, he smiled at another deaf lady who signed “I love you.” When I shook his hand it did not feel like he was superior to me. He was just a humble man. I am just impressed by him and know that he will have my vote and he will win second term without a doubt. Yeah, I feel safe to have him for another term.
