Speaking the Same Language

Sally is talking with her friend, Don. (S=Sally; D=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.

莎莉正在和她的朋友唐讲话。
莎莉:告诉我, 唐。为什么你是个西班牙人但西班牙语却说得不怎么好?
唐:那不是我的母语。我爸爸是西班牙人而我妈妈是美国人。我们在家通常都说英语。
莎莉:哦, 我明白了。
唐:你的西班牙语可能比我的好。
莎莉:对啊, 可是你英语说得比我流利。
唐:怎么会这样呢?你不是美国人吗?
莎莉:对, 可是我妈妈是西班牙人。
唐:那该不会……
莎莉:没错。我们在家大都讲西班牙语。
唐:只要我们能沟通就无所谓啦。
莎莉:说的一点儿没错。
