Again, Refilwe slanders Lerato in the most forceful way she knows how—by saying that her father is a Nigerian immigrant. This underscores just how deep Refilwe’s (and the people of Tiragalong’s) dislike of immigrants from other African countries is. It is particularly significant—and ironic—that Refilwe’s story acts as “hard evidence” to confirm Tiragalong’s biases against immigrants, since the information Refilwe shares about Lerato
isn’t “hard evidence”—in fact, it ends up being false. “Hard evidence,” then, is read as sarcastic, to highlight that Refilwe’s story is the exact opposite.
