Whether you have never met your grandfather after being born, you know that there is a grandfather's house near the school you are.When I met, my mother told me to be sour, but I visited from curiosity.It was a good man who came out.When he told him he was a grandchild, his grandfather invited him to his house with a happy expression, and was excited by the old tales while drinking tea.At the tip of the arrow, I thought, "I thought it was a bad person, but was it something wrong?"
