Once upon a time, in a cozy room, a curious boy named Nong Somchai and his mother sat together. They found a box of old pictures. The pictures were of his mother while she was still in primary school.

Some pictures were of the big classroom windows and wooden doors. In one picture, they saw a calendar hanging on the wall. The kid asked, "Which month is it?" His mother replied, "It's January." In another picture, there was a clock on the teacher's desk. The kid asked, "What color is the clock?" His mother smiled and said, "It's yellow." They enjoyed their time looking at the pictures and sharing stories.
