What is the difference between ladies aged: 8, 18, 28, 38, and 48, 58 and 68?

At 8 - You take her to bed and tell her a story.

At 18 - You tell her a story and take her to bed.

At 28 - You don't need to tell her a story to take her to bed.

At 38 - She tells you a story and takes you to bed.

At 48 - You tell her a story to avoid going to bed.

At 58 - You stay in bed to avoid her story.

At 68 - If you take her to bed, that'll be a story!!

老杨把大概的意思译一下：

8岁、18岁、28岁、38岁、48岁、58岁和68岁的女人有什么不同？

8岁：你带她上床，然后给她讲故事。

18岁：你给她讲故事，然后带她上床。

28岁：你不用给她讲故事，就可以带她上床。

38岁：她给你讲故事，然后带你上床。

48岁：你给她讲故事，是为了不上床。

58岁：你赖在床上，是为了不听她的故事。
