When I was sixteen years old，I made my first visit to the United States．It wasn't the first time that I had been abroad．Like most English students，I learned French at school．I had been to France many times．But when I went to America，I was really looking forward to having a nice easy holiday without any language problems．
But actually，I was wrong!I was looking for a public telephone to give my American friend Danny a call and tell her that I had arrived．A friendly old man asked me if he could help me．
"Yes，"I said，"I want to give my friend a ring．"
"Well，that's nice，"he said．"Are you getting married？
"Who is talking about marriage？"I thought．"I only want to give my friend a ring to tell her I've arrived．Can you tell me where there's a phone box？"
"Oh!"he said．"There's a phone downstairs．"
When at last we met，Danny explained the misunderstanding to me．
"Don't worry，"she said to me．"I had so many difficulties at first．There are lots of words which Americans use differently in meaning from the British．You'll soon get used to all the funny things they say．But most of the time British and American people understand each other!"
