Yes I do.
My lovely neighbour, very intelligent and always seemed so sure of herself, always poo-pooing " silly people" as she called them , suddenly discovered this juice ( I won't name it) that was the elixir to all of life's evils!
This juice was 'scientifically proven' to promote weight-loss, improve acne, improve joint mobility, cure my IBS, give my ( then) young children immunity from so many diseases and...reduce my chances of developing cancer!
As well as any other thing that you can think of.
Oh how she would knock on my door and tell me outright that I was stupid to not use this juice and that I was denying my family the right to longevity and that I wasn't being a good neighbour by refusing to support her new business venture and she kept asking me to take her products to my workplace so that more people would benefit from the juice's goodness.
It was so very, very hard to listen to her diatribe on my doorstep every couple of weeks but I persisted as I couldn't bear the embarrassment of my work colleagues . I , also , DID NOT WANT this blessed juice!
It was so embarrassing and toe-curling but she eventually dropped it for some kind of home craft thing.
It ruined what little friendship we had and resulted in not wanting to answer the door to anyone, in case it was her.
She moved not that long after.
