The three events that help develop the theme of perception versus reality in the text are:
- The young man reaches into his pockets in search of the soap.
- Gortsby finds the soap and concludes that the young man’s story was true.
- Gortsby believes that the absence of a bar of soap means that the young man’s story is untrue.
These events illustrate how Gortsby's perception of the situation changes based on the presence or absence of the soap, highlighting the theme of how appearances can be misleading.
