My little cousin often comes to see me. But she is too noisy sometimes. Yesterday, as usual, he came very earlier in the morning. I was listening the radio and didn’t want to play with him. So he didn’t seem to know that. He asked me to play with him again and again. I was so annoyed with him that I shout at him, “Could you just leave me alone?” He had never seen me so angrily. He burst into tear and said, “I like playing with you. When the school begins, you will leave for me again.” I was moving when I heard that. So I turned on the radio and played with him.
