Which piece of evidence best reveals the narrator’s feelings about her family’s behavior during dinner

This question is related to a short story "Fish Cheeks" by Amy Tan

Amy's parents invited the Minister and his family for a Christmas Eve dinner. However, Amy felt really embarrassed because of her family's behavior during the dinner.

The reason was that Amy's family was Chinese, they had different traditions and customs, and had a different taste in food, comparing to a typical American family. Her mother cooked all the family's favorite dishes like Fish cheeks, tofu and squid, which are usually not found on a table of an American family on Christmas Eve. Moreover, her relative ate noisily with chopsticks and were reaching across the table to get the dishes, rather them passing them. Her mother also told the guests that she made Fish cheeks because they were Amy's favorite. The worst part was the end, where Amy's father belched loudly after the dinner and explained the guests how it was a way of appreciating the food in Chinese culture.

The following paragraph can be considered as the best piece of evidence about Amy's feelings during the dinner:

"Dinner threw me deeper into despair. My relatives licked the ends of their chopsticks and reachedacross the table, dipping them into the dozen or so plates of food. Robert and his family waited patiently for platters to be passed to them. My relatives murmured with pleasure when my mother brought out the whole steamed fish. Robert grimaced. Then my father poked his chopsticks just below the fish eye and plucked out the soft meat. “Amy, your favorite,” he said, offering me the tender fishcheek. I wanted to disappear. At the end of the meal my father leaned back and belched loudly, thanking my mother for her fine cooking. “It’s a polite Chinese custom to show you are satisfied,” explained my father to our astonished guests. Robert was looking down at his plate with a reddened face. The minister managed to muster up a quiet burp. I was stunned into silence for the rest of the night."

the words “strangest” and “unusual” suggest that the narrator is about to tell the story of an odd or puzzling group of people.
