After ten years, my mother left home and my son. My grandfather persuades me to forgive him, but his son says, "I don't have anything I want you to do now." However, his son has a difficult problem to solve and he reveals it to his mother. "I've been worried about women all day. I can't concentrate on studying," she says, saying that it is impossible for her mother to do so when she is old, but the son can say more. "I want to see a woman over there. I didn't see anything important about books."
