Two sorts of people
The only two-sorts-of-people-in-the-world classification I've ever found convincing is: those people who have children and those who don't.
Criticism of parents is all very well but wait till you've been stung in domestically pressured circumstances - doting hard-pressed mum and careful but temporarily absent dad.
I am currently trying to recover from Apple £140 worth of unintentional purchases from iTunes by my 7-yr-old daughter. It simply isn't my daughter's fault that she pressed a button saying "Get free treats", but she has had nightmares and is now off school as a result of worrying about doing something wrong.
Anyone else who'd care to own up so that we can see how we might provide support in the UK for the plaintiff's case when it comes to trial?
