I was his roommate when he was an enlisted soldier in my home country, S. Korea (2000-2001). We talked a lot and definitely had a good time. He was taking some classes at that time, and we also studied together in our room. He was my best roommate.
I moved to DC area recently, and I remembered he is originally from here, and I looked him up and found that he has passed away.
I have no words to express how deeply sorry I am to hear about your loss. However, I will keep the good memory with him.
