It was a mild night in Prague. David and I spent a lovely evening in a quiet quarter of the historic city after having enjoyed a classical concert. We talked music, arts, work, the world and the universe.We laughed about our different tastes in music. It was that night I learned to know David, the father, the family man the hard working person. I admired his dedication to his family, his work ethos, his free spirit and his aspiration to learn something new every day. I respected his openness and his non-judgemental approach to new ideas. David, it has been an honour spending quality time together. We will always remember you.
