“The path of royal romance has never been smooth; Princess Margaret was unable to…” — Ingrid Seward

American manners are different than British manners.

The Middletons and the Windsors might seem at first glance to be worlds apart. Kate certainly shows no sign of adopting the horsey, doggy lifestyle beloved of her grandmother-in-law. But the Queen admires how well Kate has embraced royal life, combining it cheerfully with duty and motherhood.

When Prince Andrew tired of romancing a pretty dancer and turned his attentions to Koo Stark, he instructed the Buckingham Palace switchboard not to put her through when she rang.

The enormity of the Duke and Duchess of Cambridge's global influence is daunting, especially for Kate, whose look is admired, copied, and analysed everywhere.
