Yes! I missed the point! I am really bad about reading over things and taking them literally. Metaphors are confusing as all get out. He seems to like pencils and he sticks with them. He seems to use pencils as the "x" in his blogs. Everything happens because of this on variable that he just happens to have. He is a very smart man and he enjoys what he does and it shows. The kids respect him because he respects them.
