On a train crowded with holiday, one of three men about 70 years old who stood near by was saying “My grandchild is a sixth grader in elementary school, and menstruation came already. Recent child has growth quickly.” Because it was quite a volume, I think that people around me also heard it. He was a nice small clean guy normally, but too insane. It was surprisingly various, such as knowing such information of grandchildren and talking to his men in the train.
