Ploy has just arrived from Thailand to begin working on her degree at an American university. On Mondays Ploy was always very busy. She had classes all day and hardly had any time for lunch. One day she showed up at her history class a couple minutes before it started and told one of her classmates, Julianne, that she was really busy all morning and didn't have time for lunch. The bell rang and the teacher came into the class. Julianne opened her backpack and took out a small bag of potato chips and a can of soda and gave them to Ploy. Ploy was very surprised and embarrassed. She whispered thank you to her friend and refused the food. Ploy was even more bewildered when Julianne took another bag of potato chip and started eating them in class. To Ploy's amazement, the teacher did not make any comments on Julinne's behavior and proceeded with the class as usual.
