Charles Spencer says as Diana's coffin was lowered into the ground, several people there dropped flowers on the coffin. King Charles took a rose from Charles Spencers bouquet and dropped it on Diana's coffin.
This struck me as it shows a very casual disregard for other people's feelings. This was Charles Spencers flowers, but without a thought, king Charles took mine of the flowers. And remember relationships were extremely strained between the two men.
Sometimes I think the smallest incidents like this can reveal someone's true character. It's like someone being rude to a waiter. The king just acts like no one else matters except what he wants.
