People here are very generous; they love to give gifts and share food. When someone sends you something on a plate or in a bowl, you should return their dish to them with something in it. A couple of adult sisters recently visited me, and I served them peanut butter bars that are peanute butter cookie on the bottom with milk chocolate on the top. One of the sisters said, "You use this 'peanut butter' in a lot of your recipes, and it is not so delicious!" The good thing is that after being here for awhile, I laughed at this comment rather than taking offense!
