(CNN) -- For anyone around 30 or older, this week's royal engagement left one with an uneasy feeling of déjà vu. The photographs of Prince William and Kate Middleton, facing the flashing cameras of the world's press, were uncannily like those of William's parents, the Prince of Wales and Lady Diana Spencer, when they announced their plans to marry in 1981. The color of the dress, the pose, the linked arms, the looks -- they were almost identical. Kate was even wearing Diana's ring. The rapturous response from the media was a rerun of 1981, too -- the special supplements, the pages and pages of photographs, the speculation about who will design the dress, where they will honeymoon, where and how they first met, who their friends are and from whom their families are descended.Penny Junor: Déjà vu seeing Prince William and Kate Middleton announce engagementUnlike his parents, they've known each other for eight years, she observesKate won't eclipse Prince William; she will compliment him, says JunorJunor: Charles-Diana marriage almost destroyed the monarchy; this could secure it
