Funny. Where I work, if I show/explain/tell someone how to do something, I can either repeat the lesson every time the question comes up, or document the procedure in detail and give the person a copy. If I do take the time to document it, then I can simply reprint a copy every time the question comes up.

Now if only I had a way to handle the situation where someone attempts to perform a task, but forgets an important step or two along the way.
