The 3 Year Old Memory Aid
In the car on the way home from a birthday party, Liz and I are trying to remember names of a few people who we all met for the first time...
I suggest one was called Paul, Liz thinks he was John, but actually John was Letty's sister's boyfriend and Paul was in fact; Paul.
Hmm, but what was Letty's sisters name?
One of her sisters was called Kitty, we can both remember that one.
"Edward, can you remember what Letty's sister is called? Not Kitty but the other one. The one who arrived late."
(A short pause for thought)
"Ah, yes, that was it. Thank you Edward!"
