No. No they're not. I have no idea where you get that from.
I got that from a relative that called me tonight. She spent 7 years in the UK raising their kids there, before returning to the US. I don’t know if this was private or public school (heck, I don’t even know what kind of schools they have there!) But this was a rather ticked off relative.
She told me it is common to teach children this in the UK.
If she is wrong, please tell me more so I can hit her with it the next time she calls in a snit. :)
