Dear Editor,
I’ve read your discussion on how to behave properly while traveling. Every year, a great many holiday makers go out for sightseeing and relaxation. While they are enjoying themselves, some of them behave rudely, which causes a big concern. How to be a civilized tourist has become a heated topic.
In my opinion, it is necessary to watch our manners. First, we must respect and follow local customs. Besides, we’d better not talk loudly in public places to avoid disturbance to others. Also, be aware that queue jumping is unacceptable in many countries.
More importantly, if we travel abroad, we should bear in mind that we are representing our country, so we need to be cautious about how we act. Only in this way can we enjoy our trips and have beautiful memories as well.
Yours truly
