Personification adds to the text's mood
1. Dickens uses personification to bring the novella's settings to life - a "gruff old bell" is described as "peeping slily" down at Scrooge. Later, the onions in the grocers' shops appear "ruddy, brown-faced, borard-girthed" as they sit "winking from their shelves". These playful examples of personification make the city seem exciting and alive, and reflect the energy surrounding Christmas
2. At other times, personification is used to reinforce what's being described - in the second chapter, the joyful atmosphere is highlighted by the way the "crisp air laughed" as the boys shout to each other
3. Personification isn't just used to describe objects - it can be used to give human form to abstract concepts. The personification of "Ignorance" and "Want" as ragged, desperate children is a good example of this
