More substantively, I don’t think the problem is one of outrage, or outrage culture. After all, you seem fairly outraged at Tuvalu’s treatment yourself. Instead, the issue seems to be what people do or don’t do with their outrage. It used to be that people used their outrage to write responses and critiques of those they were outraged at. Nowadays, people seek the removal of whatever caused their outrage. You see this here but also in campus culture more generally. From what I can tell, this is reflects a generational difference; millennials seem to want anything that disturbs or outrages them to cease to exist, and some non-millennial professors pander to this, wanting to be seen as woke or something. It’s all very troubling and ultimately antithetical to the philosophic enterprise.

This particular story uses lack of proper communication to highlight the underlying theme of the paradox of human connection. Another example is Miss Eckhart of The Golden Apples, who is considered an outsider in her town. Welty shows that this piano teacher’s independent lifestyle allows her to follow her passions, but also highlights Miss Eckhart's longing to start a family and to be seen by the community as someone who belongs in Morgana.  Her stories are often characterized by the struggle to retain identity while keeping community relationships.
