英語翻譯（中譯英）

one day ,I was waiting for bus near a stop-board.An even-aged foreigner went to me,looking over the bus information.I talked with him in English,"Hi,sir,may I help you?"He replied in English at once,"no,thanks.and in veritable Chinese——“ I can understand it."I was surprised deeply and forgot to say"you're welcome",which I had practised for hundreds of times.Although I've written hundreds,thousands even millions of times,it's vain that I'm not able to say it out.Therefore,why not become friends with me?So i can reply to you"you're welcome."Then let's have a chat in English!
