64. Speaking the Same Language
Sally is talking with her friend， Don.
S： Tell me， Don. How come you're from Spain but you can't speak Spanish very well？
D： It's not my mother tongue. My father is Spanish and my mother is American. We usually speak English at home.
S： Oh， I see.
D： Your Spanish is probably better than mine.
S： Yes， but you speak English more fluently than I.
D： How come？ Aren't you American？
S： Yes， but my mother is Spanish.
D： Don't tell me……
S： That's right. We usually speak Spanish at home.
D： It doesn't matter as long as we can communicate.
S： That's true.
