what was the opinion of the narrator about sleeping . what characteristics features you'll find about him for it ???

From the text:

"I don’t know why it should be, I am sure; but the sight of another man asleep in bed when I am up, maddens me. It seems to me so shocking to see the precious hours of a man’s life — the priceless moments that will never come back to him

again — being wasted in mere brutish sleep."
