I began to understand that there were certain talkers — certain girls — whom people liked to listen to, not because of what they, the girls, had to say, but because of the delight they took in saying it. A delight in themselves, a shine on their faces, a conviction that whatever they were telling about was remarkable and that they themselves could not help but give pleasure. There might be other people — people like me — who didn’t concede this, but that was their loss. And people like me would never be the audience these girls were after, anyway.
I’ll put my answer in the comments.
