My opinion of Mary Berry is based on her attitude towards someone I knew who was at a book signing. And I will not give my opinion on here, way too much idealisation and pearl clutching going on.
In a wheelchair [not as lucky with her polio illness as Mary was] and elderly, clearly unwell, the mother of a friend presented MB's book for signing before paying for it, not knowing this was the wrong way round to do it.
She loved MB, this was a lovely day for her, she absolutely was going to buy it after signing, no doubt about that.
MB snapped at her because it had not already been paid for and refused to sign it! Appealing to any kind nature MB might have did not work! The customer would have had to have queued all over again, she had made an enormous effort to go to the venue and was then so tired.
So no one in this family or anyone who knows her watches her or buys her books.
As for being jealous of her...no way do we envy her or even think she is 'glam'! Why would we, we have our own satisfactory lives, own success and are content with what we have and how we live?
