During a training course, we had to identify whether statements were fact or opinion. I had a slight disagreement with the course leader over this one- 'Mum said that her daughter didn't eat the sweets'
One of us said that the statement was an opinion, because the truth of whether the daughter ate the sweets could not be corroborated by the observer, therefore it couldn't be considered fact.
The other said that the statement was fact, because mum did say that, and her saying it could be corroborated, regardless of whether mum was telling the truth or not.
Which of us is BU?
