seems that not everyone knows that.
Last Saturday evening, all my family members
were enjoying dinner in a restaurant when a group
of young people came in. While they were eating
their food, they talked loudly and smoked. I tried
to stop them from doing so, but they refused to
listen to me. Instead, they said it was none of my
business and laughed at me. In fact, what they did
upset me deeply, but I was proud of what I did.
In my opinion, we should keep quiet in public.
Also, we should be polite to others. Only in this
way can we be people with good manners.
