A landlord is someone who is responsible for taking care of repairs and other duties in an apartment complex, so when they don't do what they said, it leads to dissatisfaction on the tenant's behalf.
Consider the statement "When I think of my landlord I get pretty mad as they don't do half the things they promised". Is the statement "I am filled with gratitude for my attentive landlord when they don't do the things they said they would" false? Yes/no/unknown
