Costco is a fun, but busy place to visit on Saturdays. The girls love trying the many samples. Today while Elizabeth had her mouth full of some sample, Emma did something to annoy her. Elizabeth made screaming noises at Emma to express her displeasure. My automatic response was, as always, "Please use your words." Elizabeth looked at me and said remarkably clearly through her mouthful of food: "I can't use my words. My mouth is full."
