Anne was upset with Julian, her baby brother. He kept following her around the house. When she did her homework, he would sit next to her and play with her pens and pencils, or open her books and laugh at the colored pictures in them. When she played with her friends in the backyard, he would follow her there too. When she returned from school, he would run to her shouting with joy. But Anne did not enjoy Julian's "cute" antics as much as he did. And she decided to speak to her parents about it. The next day when she returned from school, she was pleasantly surprised to see Julian asleep. She felt relieved that he hadn't come running to her. She decided to call her next-door friend over to spend a couple of hours playing in the backyard. But first she did her homework. Until then, Julian had not disturbed her. Well, he must be really tired, Anne thought to herself. She felt like going to his room but she remembered her plans with her friend. What if he wakes up and starts chasing me again? I'll let him sleep, she said to herself. Soon, Anne's friend joined her and the two rushed to the backyard. Sometime later, Anne wondered why Julian hadn't come to the backyard yet. She was distracted and kept looking at the gate. "Mom, why is Julian sleeping so much today?" she called out as she entered the house after playing with her friend. "He is unwell, Anne" replied her mom. Anne's face fell. Before her mother could even complete her sentence, she rushed to Julian's room.
