I have a couple of German cookbooks, and many times the recipe calls for live yeast, so I don't really know how much dry yeast to use as a substitute -- though I assume that one can substitute dry for live.

Parents: I know what you mean. Once in a while, I'll catch myself reacting to a situation or doing something that I can picture my father doing, and even if it's something that he did before he lost his mind -- well, it just kind of bothers me.
