A few clays ago when taking the walk with my mother in the park, I came across a foreigner. Judged by his puzzled expression, I thought he might in need of help. So I went up and asked what I could help him in English. He told me he had got lost. He had turned to several passer-by for help, but he couldn’t speak English. Then he told me his destination. Fortunately, I was quite familiar with the place. In order to make myself understand, I told him how to go there as clear as possible. Although it was the first lime that I have talked to a foreigner face to face, he totally understood what I said and thanked for me.
