I often wonder why I exist in this world at all. What is a real meaning of my existence? Since I don't/can't have any children of my own this is even harder to know and understand. From time to time I get a proof that my existence in this world is not quite in vain. On Friday four Slovenian bird stamps will be issued. They wouldn't be if I didn't exist. But at the same time I ask myself - would be there really any difference if they weren't issued at all?
