Daddy must have promised to take him to A&W. As soon as Daddy got into the car, Wyng demanded that Daddy took him there. When Daddy said, 'Did I say I want to take you there?', Wyng snapped with a 'Short-term memomy loss!'.
Mom's mind was thinking, 'What's that? Oh, forget. Can't he just say forget?' He learnt this phrase from a book he read. Not sure which one. Gotta find out from him.
From that day onwards, he seldom used the word 'forget'. He prefers to use that phrase.
