On the third day nothing happened, and I began wondering whether I should 
go into the cave and look for Dojo. So far the only living thing I had seen 
around here was a
black mouse that occasionally darted out from the rocks at the cave's entrance, 
foraging for a bit of food. The next time I saw that mouse, I said (speaking 
softly so as not to scare it), "Say, mouse! Is there anything back inside that 
cave?"
