Thornton knelt down by buck's side. he took his head in his two hands and rested cheek on cheek. he did not playfully shake him, as was his wont, or murmur soft love curses; but he whispered in his ear. "as you love me, buck. as you love me," was what he whispered. buck whined with suppressed eagerness.
what does buck’s whine represent?
his love for thornton
his sore body from running
his fear of the task
his inability to pull the sled
