An answer to an LJ community challenge, subject, "rain". I'm not sure if a non-British audience will be familiar with the original story, but I like it.

  It was cold and wet, even inside the shelter of the cave. The rain got in  everywhere, dripping from the roof, trickling down the slimy walls. He had  attempted to light a fire, but the tinder was damp, and the sparks from his  steel died into nothing. Failure again. Instead, he had shivered through the  long night, stomach cramping with hunger, back cramping with cold. With the  first light, he watched the valley below for movement, and closer, watched as a  spider tried to repair a web that the rain was tearing apart. There was nothing  else to do, and he did not want to think further.
  
  A man was walking up the stream bank, plodding slowly, wearily. He knew him,  knew what he would call up to the cave entrance.
  
“Is the Bruce within?”
  
  He did not want to answer, to admit to it, but: “Aye.”
  
  A dark shape silhouetted against the grey sky as the newcomer entered, stood  there over him, cloak dripping. “A miserable day.”
  
“Aye.” There was nothing more to say, or too much.
  
“So, Robert, are we going back? Is it worth trying again?”
  
  They would do it, he knew, if he asked them. Again, and again, losing more men  each time. He stared at the ground, at the trickle of water that ran from the  cave, almost ashamed to be the object of their loyalty. The dead, water-logged  spider floated past, and was gone, down the hill, into oblivion.
  
“No. Enough is enough.”
