Kate Middelton politely declined signing autographs at her appearance on Monday at the Chelsea Flower Show. The Princess of Wales, 41, made a surprise visit at the inaugural Children's Picnic where she shared an unspoken royal rule with a few elementary school-aged kids. "I can't write my name," Middleton said, according to People magazine, "but I can draw."  The outlet reported that the princess drew a flower for a 7-year-old girl named Ruby, a tree for another young girl and a pond with flowers for another child. "My name's Catherine.

I'm not allowed to write my signature, it's just one of those rules," Middleton told the children when asked why she could not sign her autograph, the outlet reported.

During her surprise outing to the Royal Entomological Society garden, Middleton shared with the children attending that her youngest son, Prince Louis, is taking up some gardening himself. "Louis is growing broad beans at school.

You put them in a cup, and you can see the roots growing.They get big quickly like sunflowers," Middleton said. Middleton shared with the school children the importance of spending time outdoors. "It's so good for our bodies and our minds," she said.
