I will give you a small example. A nice lady had a new maid. In order to entertain a friend, who was coming to visit her, she asked the maid to go and buy a beautiful bouquet of flowers. When the maid went out and asked the price of the bouquet at the florist's, she thought, "How extraordinary on the part of my lady to spend all that money on this. I wish she would have asked me something else to do." Instead of doing what the lady had asked her she went and bought some cheese sandwiches, and was delighted in her heart thinking, "When I bring these to my lady she will be very pleased." When the lady saw what the maid had bought she was horrified. While she had expected that her friend would be entertained with flowers, there were cheese sandwiches!
