"Charles would eavesdrop on some of the 30,000 annual tourists who pay 15 pounds each to tour his 900-acre royal estate in Gloucestershire."
“He would lay face flat on the floor with his eyes closed and ears in concentration.”
This doesn’t come as a surprise. In a 2010 BBC interview, the 70-year-old admitted that he does in fact eavesdrop on what visitors say.
"When they're going 'round outside the windows. Sometimes you've got to lie on the floor."
Charles also revealed that he talks with the trees and plants in his garden.
"I happily talk to the plants and trees, and listen to them. I think it's absolutely crucial.
"Everything I've done here, it's like almost with your children. Every tree has a meaning for me."
