Welcome back to the red couch scene, so obviously this is the end. And we would like to thank everybody's participated in the class and gave us feedback. It was an incredible experience. We are both, Paolo and I, very glad it's over, and I'm sure many of you are also glad it's over. But it was an incredible experience, and we would like you to, we would like to thank you very much for your feedback. So it was a lot of effort for us but it was great to see the activity in the forums both in terms of the feedback that you gave us, and in the way you helped each other out. And we would like to thank you also for spotting all the mistakes that were made in the slides and in the book, and provide us with very, very fruitful feedback to correct those mistakes and make the course even better. >> Let us encourage you to fill in the survey even if you drop the class. It would be great if you give us feedback why you dropped the class. And if you're hanging in there tell us what you liked, and what could be improved because we are going to work on an [UNKNOWN] of the class, and your feedback is extremely important. And as musician's say, without an audience we would be nobody, and so thank you very much for being a great audience. >> So we got to take a break, because we need it very badly. But we will be back in the fall. So those of you who had to drop out because of other engagements will be able to take the class again probably in October. So stay tuned for announcements in that sense. >> Indeed it has taken a toll on us and I counted carefully the gray hair on Paolo's head. >> [LAUGH]. >> And it's aug, augmented by 17%. >> [LAUGH]. >> I can testify. for those of you who finished the class and fill in the homework, and pass the class. You will receive a certificate within a couple of weeks and congratulations. >> Absolutely. So thank you once again. And hope to see you again. >> See you.
