My mother, too, put her foot down firmly on chain letters and convinced me that bad luck would not be a consequence of breaking the chain. She told me that only silly supersitious people believe in such nonsense.
I think I was 11 or 12 at the time.
Her attitude stood me in good stead as after computers and e-mail became part of every day life the chain letter turned up as e-mails, which I ignored.
In between whiles we had the friendship cake, and the knit squares of such and such dimensions and send to the four people on the list and after three months you will receive a knitted blanket. Ha! Ha!
The cake also cropped up.
Finally, the email from impoverished school teachers in some third world country asking for donations to their schools, widows from Latin America needing help to support their children, plus the hairy old chestnut the unknown grand-uncle in Australia who had died leaving one a fortune and all you had to do was to send your bank details turned up in cyber space.
I never believed any of them, and attibute this to my mother's attitude to chain letters.
