“I admit that I had some fears at the beginning since my D.E.S. had come a long way, but your way of making a sometimes heavy subject much simpler in part thanks to the humor so there hats off, moreover I would like to tell you that it is by far the best training that I have received throughout my life. If I would have had you as a high school math teacher, I might have become a statistician!​”
