Wouldn't it be appropriate to reply that I was not interested in your opinion about frying potatoes yes or no?

Seems like the "better" is in the eye of the reader. Anyway, there were about two hours between the time I started writing this and now (work has this habit of interfering :), so now I've completely lost my train of thought, and can't remember what I wanted to say.
