2-- If they are just like us, they are not middle-aged.

1-- Of course they are.

2-- Middle-aged means in the middle, Ethel, middle of life. People don't live to a hundred and fifty.

1-- Oh, we are the part on the edge of middle. That's all.

2-- Oh, you know, we are not middle-aged. You're old, and I'm aging.

1-- Oh, fool! You're nearly seventy and I'm in the low sixties. Would you like to spend the rest of the afternoon squabbling about this?

2-- I can if you like.

1-- 他们是一对幸福的中年夫妻，就像我们一样。

2-- 要是像我们一样，他们就不是中年人了。

1-- 当然是。

2-- 中年意味着在中间，埃塞尔，一生的中间时段。可是谁也活不到150岁。

1-- 哦，我们是在中年的边缘，如此而已。

2-- 你知道，我们不是中年人了，你老了，我也不年轻。

1-- 哦，傻瓜，你快70了，我也是60多。你打算就这一点和我争论到天黑吗？

2-- 行啊，只要你愿意。
