The use of phrases like "black veins," "slimy rock cod," and "bulging eyes" really hammers home Tan's point about how different/embarrassed she felt. She is definitely emphasizing "weird" aspect of the dinner. It does make you empathize with her and feel bad for her, especially considering that Robert is there.

I like how Tan uses this effective hook to get the reader interested in reading the story. Off the bat, it helps you resonate with her -- she is being open, vulnerable, straight-to-the-point, and relatable. Pretty much everyone has felt this. I think that it is a great way to start.
