Making your Mom deal with permissions? Yikes.

I think reasoning, in addition to basic instructions, is important even though some people might not care about it. By leaving it out you deny those who do care an opportunity to learn.

And to me it just seems more respectable when someone asks you to do something and tells you why you are doing it then if they just give you bare instructions. (That said, the bare instructions should be able tostand on their own. They had better work, every time.)

Moreover, providing reasoning forces you to demonstrate you know the subject matter well enough to be able to explain it.
