Prince William and Kate Middleton celebrated their fifth wedding anniversary on April 29, and (with a fan base that rivals that of One Direction) they naturally got a ton of mail. But instead of ignoring congrats from the commoners, the Duke and Duchess sent thank you notes to literally everyone who took time out of their schedule to wish them well.
In the words of Doge, wow. Such polite. So royal.
Even better, the duo printed their thanks on the back of a brand new portrait wherein they're looking 50 shades of regal.
So fab.
P.S. This isn't the first time Kate and Will have sent out thank you cards. They issued a few kind words after Kate announced her first pregnancy, and after the birth of Prince George.
