Summary
Analysis
When Tomas closed his book in the restaurant of the small Czech town and motioned to his waitress, who happened to be Tereza, Tereza took note of the book. He told her to charge his bill to his room, which he said was number six. Tereza thought of her childhood home, whose address was six, but she didn’t tell Tomas this. Instead, Tereza told Tomas that it was curious that his room was six, since her shift ended at six. When Tereza left the restaurant at six o’clock and found Tomas waiting for her in the park across the street, she knew Tomas was indeed her fate.
Each one of these happenings that Tomas sees as chance or coincidence, Tereza sees as fate. Again, meaning and interpretation are subjective, not consistent or universal. Tereza’s childhood home appears again near the end of the story. She visits the house during a dream, and the night before she and Tomas are killed in a car accident, their hotel room looks very similar to Tereza’s childhood bedroom.
