People always said taht the first impression is very important.It was true ,my math teacher, for example,when the frist time i met him ,i think he would be a strict and serious person for he always frown .
The math teacher is a middle-age person who is short . wearing a big glasses on his nose and always a brown suit which gives me a sense of humor.His humor comes from his never varegated voice,which made his words sound very interesting even the usual contents .Maybe, he may not realize himself humourous.
He seems pretty strict, but he was not a cantakerous person as you thought.In fact,we haven't saw he lose temper before.Insted ,he teaches very well which made me fond of math for the great math teacher.
People always claimed the importance of first impression,but it‘s not the vital one to judge a person ,becaus the rigorous and serious teacher also gaves me an great experience.
