Classic Chocolate Chip Cookies

This is the best chocolate chip cookie recipe. David has taken over the task of making these cookies and he does it well. One time Helen tried, but she put baking powder instead of soda in them. David was quite scornful, concluding that only HE could do it correctly. They turned out differently, but were eaten nonetheless, even by David.
