Final answer:
The central idea of the excerpt from Warriors Don't Cry is that the narrator cherishes her rare worldly experiences, which include attending events in a usually segregated space.
Step-by-step explanation:
The central idea of the excerpt from Warriors Don't Cry is that the narrator cherishes her rare worldly experiences. This is evident when the narrator describes attending matches at the Robinson Auditorium, noting that it was a significant event because it was a place 'usually reserved for white people only' and it allowed her to step outside her usual surroundings. The use of phrases like 'big events in my life' and 'able to observe them close up' points to the value placed on these experiences where racial barriers were less pronounced, and she had the opportunity to be in the same space as white people, which was a rare occurrence due to segregation.
