Ove's worldview leaves little room for aging and the things that come with aging, such as illnesses that could make someone non-functional. This again speaks to how much stock Ove puts in being “useful,” as it's entirely beyond him that people who aren’t traditionally functional can have value. Parvaneh continues to show that she's not afraid of Ove and is willing to match him in belligerence. At the same time, she’s clearly trying to make him engage in the community. It should be noted that helping people perform these tasks does fall in with Ove's sense of principles and loyalty, despite his unwillingness to do them.
