This is the story from the past of brother A and his older sister L, who are among us.
One day, a bunch of girls came over to their house, and sister L was playing house with them. After a few minutes, brother A came out to the living room to their parents, crying.
"What's the matter?" said Mrs. Tung.
"She's playing house with her friends, and she won't let me play!" cried brother A.
Mrs. Tung went over to L's room where the girls were playing, and said, "Look, you let your younger brother play with you, okay??"
"Okay," said sister L pleasantly, before welcoming brother A into her room. Brother A went into the room with a beaming smile, and their mother went back to the living room, satisfied.
After 30 minutes, Mrs. Tung decided to check up on them and went upstairs. To her surprise, she found brother A alone in the hallway on his knees and hands, in front of the closed door of his sister's room.. But he was not crying - he seemed happy.
"What are you doing?" asked Mrs. Tung.
Brother A smiled and said, "Oh, I'm the family guard dog."
