An extremely ancient couple were worried that they both kept forgetting little things, so they decided to write each other little notes.
One day, the wife said to her husband, "Please go into the kitchen and get me some ice cream. Now, do you want me to write a note so that you'll remember what I want?"

"Absolutely not! "he said. "I can remember a little thing like that, without you writing a note!"

"Well," she said, "Would you please put some strawberries and cream on my ice cream as well? Do you want me to write a note?"

"Absolutely not!" he retorted. "I can remember all that quite easily without a note!"

So off he went into the kitchen. There were quite a few minutes of pots and pans being crashed around. Eventually he came back into the sitting room and presented his wife with a plate of bacon and eggs.

"Oi!" she said, "Where's the toast I asked for?"
