documents: #Person1#: Hey. Owen! Have you gone on your family vacation yet?
  #Person2#: Oh, yes. I got so tired. My son began to cry the moment we got on the train. It was very embarrassing because we took the over-night train and the noise made it difficult for other people in the cabin to sleep.
  #Person1#: Didn't you bring his favorite toy?
  #Person2#: Yes, we did. Fortunately we put his Teddy Bear in the bag, and finally he fell asleep at mid-night with it in his arms.
  #Person1#: Where did you go? You've got a beautiful tan.
  #Person2#: My wife didn't like to go to amusement parks, so we compromised and finally went to the seaside. I think vacation in summer is not good.
  #Person1#: You must have had a great time. Most children love to play in the sand on the beach and go swimming.
  #Person2#: Yes, he was every excited to see the blue sea and picked up many seashells to give as gift for his classmates in kindergarten.
  #Person1#: His friends will be very happy to get the little souvenir.
  #Person2#: And I taught him how to swim in the sea. It was fun and made him braver than before. After we returned home, he wasn't afraid to sleep alone in his bedroom.
