That Full Feeling

Setting:
Two sisters have lunch in their home.
Sister 1: This food is so good!
Sister 2: Thank you, I am so glad this new recipe worked out.
Sister 1: Who knew you were such a good cook.
Sister 2: I am going to save the rest for Bob.
Sister 1: I need seconds.
Sister 2: If you wait you'll feel full. It just takes time for your food to register.
Sister 1: I need to hurry before I feel that!
