Every family has to donate six dozen cookies and then the community comes out to choose a variety of their favorite cookies, which then makes it unnecessary to bake their own cookies.
It's a pretty good system and I love it, because people pay me to bake their six dozen. I don't, however, participate in the actual purchasing of other cookies. It grosses me out. I don't know what kind of kitchen those cookies came out of, or if you smoke or washed your hands or had the flu. I can't help it.
But, if you are my friend and you bake for me, I will accept your gift. I have been in your house, after all.
