Answer:
Contentment sidles up beside him 
Explanation:
The personification is the figure of speech that promotes human characteristics for inanimate objects or animals, causing a feeling of anthropomorphization. You can see an example of this in the text shown above in the line "Contentment sidles up beside him." That's because "Contentment" is an inanimate object and it would be impossible, in the real world, for it to have the ability to sidle up beside anything, which is a human capacity.
