Final answer:
There is no information provided in the provided excerpts about Dolores Epstein or her reason for being in the principal's office, therefore an accurate answer cannot be determined without further context or specific text references.
Step-by-step explanation:
The provided excerpts do not contain specific details about a character named Dolores Epstein waiting in a principal's office, hence it is challenging to confidently determine the correct context or answer as to why she would be there. Without a specific text reference, any answer given would be speculative and not based on factual information from the presented texts. Therefore, I'm unable to provide an accurate answer to the question 'What was waiting for Dolores Epstein in the principal's office and why?' based on the available information. I recommend reviewing the text where Dolores Epstein is a character for the correct context and information relating to her situation.
