Protrude his tongue

My younger brother, Shintaro is in the full vigor of rascal. He often plays up toward me and his older sister.
For example, he always play catch ball with his younger brother. They have strength enough and to spare, so it is good thing. However he doesn’t know between right and wrong. He plays near our car, and doesn’t obey my instruction. Because of the cause, he always fails and is scolded. I want him to be little obedient. When he played up, he protruded his tongue. I think that he is dear my brother, but I have hated him then. (101 words/190 words)
