A blow which does not even find its mark

"Strangely enough, a blow which does not even find its mark can, under certain circumstances, hurt more than one that finds its mark. Once I was standing on a railway track in a snowstorm. In spite of the weather our party had to keep on working. I worked quite hard at mending the track with gravel, since that was the only way to keep warm. For only one moment I paused to get my breath and to lean on my shovel. Unfortunately the guard turned around just then and thought I was loafing. The pain he caused me was not from any insults or any blows. That guard did not think it worth his while to say anything, not even a swear word, to the ragged, emaciated figure standing before him, which probably reminded him only vaguely of a human form. Instead, he playfully picked up a stone and threw it at me. That, to me, seemed the way to attract the attention of a beast, to call a domestic animal back to its job, a creature with which you have so little in common that you do not even punish it."
