"You havent eaten it.. have you!"

'Whats that there?.....
'Where?'
'There, she says.. pointing at my chin.
'I dont know, i say...
'It looks like chocolate is it?'
No answer.
'Is it?'
'I dont know'.
She goes to the cupboard...looks in..top-middle-bottom,
turns back to me.
'Its gone.. its gone...
'You havent eaten it, have you?'
'I dont know'
'You dont know.. you dont know if you've eaten a whole chocolate cake or not?...
When?... When did you eat it?'
So i told her.......
