Write it down

An elderly couple had had a good marriage for many years, but now they 
both had trouble remembering even minor details of their lives.  Their 
marriage continued to work anyhow, because even in CRS they were in unison.  
For example, one day the man said he'd go out to get some desserts for them. 

The woman said: " I want a sundae with 3 scoops of chocolate ice cream.  
Write it down."  

The man said:" I don't need to write it down."  

The woman said: "And I want whipped cream on it. Write it down."  

The man said: "I don't need to write it down."  

"And," the woman added, "I want chocolate syrup on it, too.  Write it down."  

Again the man said, "I don't need to write it down."

So he went out and returned home and then handed his wife a plate of eggs and 
bacon. She looked at it and asked: "See, I told you to write it down.  
Where's the toast?"
