Mrs. White is worried about her weight, so she goes to see a doctor. "Oh, I'm too fat, I need to lose a lot of weight." "It isn't difficult to lose weight," the doctor says.
"All you need to do is go on a diet. I'll give you a method. "The doctor takes out a piece of paper and writes, "Eat lots of fruit and vegetables. Also, eat a lot of lean meat and grains." The doctor gives the paper to Mrs. White. "Eat all those things and you'll soon lose weight."
A few weeks later, Mrs. White's friend visits her. Her friend sees that Mrs. White is even fatter than before. She is eating a huge sandwich with chocolate and ice cream now. "I thought you were on a diet," her friend says. "Oh, I am." Mrs. White answers. "I've already had all the food on my diet today. Now I'm having my dinner."
