It's wrong to snoop.
Sally has been invited to her friend Beth's house for lunch and Beth is on a diet.
Sally wants to know if Beth is eating lots of low calorie foods.
Sally asks Beth if she eats all low calorie foods since she's on a diet.
After lunch when Beth leaves the room Sally looks in her fridge to see what she eats.
Beth laughs and tells Sarah that she tries to but sometimes she slips up and cheats a little.
Beth comes back in the room and catches Sally being nosy.
