We should behave well not only in public but also at home.

Dear students,

Most of you behave well in public. But I think you should have good manners at home as well. Here are my suggestions.

First, talk with your parents as often as possible. (1)Some students are impatient. They don’t talk with their parents.

Second, respect (尊重) your parents. (2)Some students are rude. They can’t keep their voice down when talking with their parents.

Third, try your best to help your parents. (3)You should be helpful and do some housework.

If you follow my advice, you will enjoy yourselves at home.
