A lion is having its relaxed siesta in the forest. It is absolutely silent.

A stray dog is just standing somewhere near and is barking its heart out seing the lion. The lion just ignores the barks because it thinks that it would be a useless exercise to use his own very sharp fingernails which are capable of shattering the forehead of an elephant in rut, just to ward off the nuisance of a silly dog.

However, noticing the silence of the lion, the dog is increasing its barking thinking that the lion is afraid of it.
