Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I would draw your attention to a few of our laws.

The first one is drinking. Now, you may not buy wine in this country if you are under 18 years of age, nor may your friends buy it for you.

Secondly, noise. Enjoy yourselves by all means, but please don’t make unnecessary noise, particularly, at night. We ask you to respect other people who may wish to be quiet.

Thirdly, crossing the road. Be careful, the traffic moves on the left side of the road in this country. Use pedestrian crossing and don’t take any chance when crossing the road.

My next point is about rubbish. It isn’t lawful to drop rubbish in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a dustbin.

Finally, as regards smoking, it is against law to buy cigarettes or tobacco if you are under 16 years of age.

I’d like to finish by saying that if you require any sort of help or assistance, you should contact the police, who will be pleased to help you. You can call, write or directly go to ask any policeman.
