Point 2: Bob and scrooge.

• "But he couldn't replenish it, for scrooge kept the coal box in his own room" = this shows that scrooge is cruel to Bob because he is depriving Bob of the ability to have more coal because he is keeping it stored away from him.
• "Tried to warm himself at the candle." Shows that Bob would rather use the very very little warmth he had. Rather than challenge scrooge and potentially provoking him. This implies that scrooge was very cruel to Bob and Bob is scared of him because of it.
• "But his clerks fire was so very much smaller"
