Where are we?

上完钢琴课回家的路上，小菜欢呼：

--Yeh~~~~~~~Look, I saw an American flag!! Are we in Washington DC?

--Well, yes. We are very closed to DC.

--Then are we closed to the earth? I know Washington DC is on the earth!

--Well, you know ,we all are on the earth.

--Oh......

听得出来小菜很失望这个结论，她还以为自己有了什么伟大的发现呢，:P
