What is the meaning/central idea statement for "My Jockey" by Lucia Berlin?

The central idea is the irony between the love the jockeys that come into the ER she works in have for their sport, despite their small frames and fragility

Explanation:

She focuses on how the particular jockey she is treating is small and scared, how he calls out for his mother, how she has to carry him around, but still wants nothing more than to race the next day
