誰幫忙把這個笑話翻譯成英文，感激不盡

An English beginner was walking on a street one day, and stepped on a foreigner's foot by accident. The beginner hurriedly said :"I'm sorry." And the foreigner replied "I'm sorry too" out of politeness. But the beginner became nervous and said:" I'm sorry three." Puzzled, the foreigner asked:"What are you sorry for?" " I'm sorry five.."said the beginner helplessly.
