Memory Loss

Once there was an old couple who went to the doctor for their checkup. They were told that nothing was physically wrong with them, but that they were both suffering from memory loss, and may want to start writing things down.
That night when the couple is at home watching TV, the old man gets up from his chair.
"Where are you going?" the curious wife asks.
"To the kitchen."
"Okay. Can you get me something while you're in there?"
"Sure. What?"
"I'd like some ice cream please."
The man starts to walk into the kitchen. The wife asks, "Shouldn't you write it down?"
"Nah. I don't need to. You want ice cream. I can remember that."
"Wait. I just remembered. I want strawberries on it too. Shouldn't you write it down? I'm not sure you can remember all of that."
"I told you, I've got it. So you want ice cream with strawberries on top?
"Yes. And oh! I'd like some whipped cream too if we have some. Are you sure you don't want to write that down?"
The husband is irritated now. "Yes! You want ice cream with strawberries and whipped cream! Geez!" He walks off into the kitchen muttering to himself.
Twenty minutes later, the husband comes out of the kitchen with a plate of bacon and eggs, which he places in front of her. She just kind of stares at it for a minute, then looks up at him. "Where's my toast?"
