I always wanted to give the very first class in a master, because at that moment, they dont know each other and they are starting a new chapter in their lifes, coming back to another that they most likely had left behind some years ago.

I never had the chance since I teach mostly optional classes at the last or second to last semester.

Finally this semester I was able to do it and not only that, this class was the first class ever, since the master in data science just started, so I was able to teach at first semester, the first day on a newly created master.
