It is only few month ago, Chris and Yuqing invited me to their house on a raining winter Sunday for a hot pot party as my very first visit to Derry. Chris thought Geoge to write my name on his writing borad while Yuqing was preparing the dinner for everyone. Later, Geoge put a tail on himself and running around the house, laughing, when we were sharing the experience of raising kids since we are on the similar stage as parents. I can feel the love and happyness in the family at that moment. And I will remember the moment in their house and the heartbroken feelings I had when hearing Chris’s passing. Yuqing, I can’t imagine how you feel and how difficult this must be. My deepest condolences to you and Geoge.
