I wanted to answer big questions about humanity, about how it is that we understand about the world, how we can know as much as we do, why human nature is the way that it is. And it always seemed to me that you find answers to those questions by looking at children.
I'm not a fan of small talk but if you want to get into the big questions of life - your deepest regret, your greatest joy - then we're going to have a great chat.
When it comes to social issues such as the role of the family, I'm certainly more conservative than Angela Merkel. But on the big questions on what direction and where Germany should develop, when it comes to the economy, then we have very similar views.
I believe that young people are looking for answers to the big questions just like everyone else, and that they respect intelligent comment to help guide them through tough times.
I've always been slightly preoccupied with death or whatever those kind of silly big questions people will tell you to not spend your time worrying about.
