Dieter: Yesterday, I taught the basic aspects of the game to a newcomer. Then he played one of our clubmembers. I told him incidentally that he should put down the three stones so that White's lower right corner remained empty. Next, I played another clubmember. We wished each other good luck with the game, saying "Onegaishimasu" - or whatever it should be. It occurred that the newcomer was struck by both habits of politeness. He later asked "Should I know other things ?"
I will most certainly include those GoodHabits in my next "first session" and include others like how to hold and play a go stone in second and third sessions. People usually get overwhelmed by too technical explanations. They just love it when those side aspects come into the picture. And I remember I did.
