Woman’s life story…

What is the difference between girls aged: 8, 18, 28, 38, 48, 58, 68, and 78?

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 — She tells you 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!

At 78 — What story?  What bed?  Who are you?
