kirschner, I still have to realise that this really happened: Was reading Ada & #Zangemann at a school to 80 children (3+4 graders). There was a great and long discussion about their ideas for inventions and many questions about the book. Afterwards they asked me to give them autographs on their arms, hands, shoes, a poker card, ... (there was no paper around) and when I was leaving the school for my train ~30 of them were running next to me, thanking me, and asking me to do high fives with them.
