Excuse me, may I sit here?
Yes, please.
Thanks.
Where are you going?
I'm going to Washington D.C. And you?
To New York. Is this your first trip here?
Yes, I am a student from China. Would you please tell me something about Washington D.C.?
With pleasure. Washington D.C. is the capital of America and it has many interesting places.
But I am afraid I won't have enough time to see all those interesting places.
It doesn't matter. You can take the tour mobile. It will take you to most tour sites in Washington D.C.
