My mother, father, stepmother and surrogate mother have all died of cancer; my best friend has got terminal cancer and at least five of my other friends have had cancer but survived it.
I don't think I've got the expertise with which to nit-pick, and I freely admit that my motivation to support charities has been emotional, rather than as a result of being particularly well informed as to how the money is used.
I was accorded the opportunity to learn by failing - albeit at the cost of a few honourable teachers' sanity - and now I realise what a rare and incredible luxury that is.
