我站起来，摇摇晃晃地，试着把脸挺直。

And then, before I could straighten my face, he turned back to me.

然后，我还没来得及直起脸，他就转身对着我。

I froze briefly, made to straighten my face, but before I could, the corners of her mouth twitched, like her daughter's, almost as if she couldn't help herself.

我愣了一下， 正想直起脸来， 但还没来得及，她的嘴角抽动了一下， 就像她女儿一样， 几乎是情不自禁似的。
