A Teacher

When I hear a slow footstep on the stairs, that means Mr.Huang is coming. He is our math teacher at school. He likes to smoke, so when we recieve our test results, we sometimes catch the smell of smoke. He has a large bald patch on his head that gleams when sunlight shines in the classroom. He is tall and very thin, and he wears glasses. His favorite hobby is reading out our bad grades and reporting them to the homeroom teacher so we will get a scolding. He is about fifty, so his thoughts are a bit strange. He is a strange teacher, but almost everyone likes him because he is funny when he is happy.
