Another circle for the Venn diagram is that the schizophrenic sister's name happens to be Carol, the same as the name in the ad shown on the fridge.
Obviously made up.
> the schizophrenic sister's name happens to be Carol ... Obviously made up.
Why? because no-ones' sister is ever called "Carol" ? Or because people of that name don't get schizophrenia?
I consider myself sane, but if I saw a billboard addressing me by name, I would do a double-take at least. I can easily understand how it would have an impact and look like a schizophrenic symptom.
The TV show advert with that text actually does exist, I've seen it.
Given that, what are the odds that some day a) it is seen, b) by someone called Carol, c) who is susceptible to being affected by it. I would say substantial.
We don't know the truth of this at all.
And why did it have to be a fridge? The same ad is being displayed all over the place, from phone screens to billboards.
