What did Izzy remember about a visit with Parker's parents?

Izzy remembered last weekend when Parker's parents came to visit. They took them out to eat for a meal that cost half of what Izzy made in a week. They went to a steak and seafood place where the food was airlifted in from the North Sea or a ranch in New Zealand. Parker's father ordered a seafood tower. Izzy did not know how to eat the food or how to behave. Parker's mother talked about the work she did with the hospital auxiliary, and Parker's father asked her questions. When they talked about their recent trip to Paris, they told Izzy that she and Parker should come next time. Izzy relaxed, but then tried to eat a piece of shrimp without peeling off the skin. She went and hid in the ladies' room. Parker followed her and proposed to her.
