我还是个少女的时候，妈妈就和我说德语，可是，入乡随俗，到了美国，你就会和大多数人一样，不由自主的说起了英语。

My mother and I spoke German to each other until I was a teenager, when, like many children of immigrants, I started refusing to speak anything but English.

一般地，我们会不由自主地说，“我知道那是什么意思“,或者，如果我们不知道它是什么意思，我们会说，“它一定有某种意思，虽然我不知道究竟是啥意思

Ordinarily, we just spontaneously say, "I know what that means," or if we don't know what it means, we say, "It must mean something even though I don't know what it means."

我不由自主的说，这真是个免费的国度啊。

Hey, it's a free country.
