A basic lack of knowledge

At lunchtime I was working out how many calories I'd eaten and I decided I could have a banana even though it took me slightly over my lunch allowance because I hadn't had my mid-morning power snack.

'I beg to differ,' said Husband. 'I think you did.'

'No I didn't.'

'What about the three large chunks of cheese you had at Sainsburys?'

'For goodness sake! Everyone knows that free samples don't have any calories!'

Husbands just don't know anything about dieting.
