To get a woman to bed!

What is the difference between taking girls/women to bed at the following ages: 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 so you can take her to bed.

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

 

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 WILL be a story!

 

And at 78 -- What story??? What bed??? Who the hell are you???
