I finally got to meet Kwang's 94 year old grandfather over Chuseok. He is Kwang's maternal grandfather. Personally I don't think he looks a day over 80. He has an apartment in Busan, the second largest city in Korea. He even still rides a bicycle!
He is such a sweet man. Unfortunately, his hearing is going and it's hard for him to hear unless conversations are shouted. He was very excited to have the company.
