Thus the sign on a young man’s T-shirt, which I just spotted in the center of Zagreb.About twenty, as well as rather slight and even frail, he was walking along one of the main streets together with two or three of his friends the same age and appearance. Anyhow, it is difficult to explain how happy the sign made me. I was sort of ecstatic for a moment or two, especially because the young man bore no visible sign of his professed calling. Minus his T-shirt, that is. Which is why he struck me as so much more credible, too. Would that the sign on his chest worked as well with apprentices of his fancy rather than silly old geezers like me!
