In our experience, most people give horrible directions. It's not just that the directions are often inaccurate. It seems as though concentration on the information subtracts from the coherency of the speech delivered. We had to spend a full 8-hour day filming over 220 people in order to get a dozen usable examples for this lesson.
In the editing room, we soon noticed that we had chosen the simplest replies to our questions because only the short replies were grammatically correct. Our interviewees decided for us that this lesson would be most accessible to beginners and pre-intermediate students instead of those at a truly intermediate level as we had originally thought.
And so it goes in the world of real English...
