What is the personification in the story the landlady?

Situational irony is shown in "The Land Lady" by Roald Dahl when she poisons him. This is situational irony because the reader does not expect it to happen. An example of situational irony is shown when it says "Everything is always ready day and night in this house just on the off-chance that an acceptable young gentleman will come along" (pg 2, para 16, line 185) and when it says "I stuff all my pets when they pass away" (pg 5, para 27, line 475). This example is situational irony because the reader is not expecting that the woman would stuff the "acceptable young gentlemen."
