Answer:
Beneatha’s desire to use their father’s life insurance after his death to go to medical school annoys her brother Walter. Walter thinks that studying medicine isn’t a womanly profession, and he worries that the tuition cost is too much of a cut of the check. Beneatha, who is angry, sarcastically asks her brother to forgive her for having a dream. Like all of the characters in the play, Beneatha has a dream that is just out of reach.
