One day I showed my training host brother, Samon, how to build a simple card tower with a deck of cards I brought from America. I didn't know if he got anything out of it at the time. A couple days later I was reading outside, and he came and tapped me on the shoulder and pointed at the table inside. Behold!, the largest card tower I had ever seen. I was thoroughly impresed, and I think he noticed when I took a picture of him in his card tower. He was very proud.
