I was worried about my son's way home from school because he had never walked any streets without adults. Moreover, although my daughter had told me he would get off school earlier than her today, in reality she got home first. She didn't see him after class. I was frightened and ran to school, then I found him at the inside of entrance. He was talking with his friend. I scolded him for making me frighten and warned him that I would call police if he hadn't gotten home on time. He tried to explain me something, but apologized me for his fault finally. At home, my daughter was waiting for us with fear.
