Being Dad isn´t easy - being kid either. In a way what a strong man he was. Brought up five kids. How strong he was as he were young, full of power like a strong Diesel. He loved cars, motorbikes, lorries all these vehicles so much. Took a car in pieces and reassembled all these pieces to a car which wasn´t the same than but better. Built a house almost alone with his own hands. Showed me how fascinating Chemistry is, how beautiful Music is, how fascinating reading is. Thank you for this book on Toxicology. Thank you. I am sad that you are gone now. Your birthday will never come back. But in my memories you´ll be.
