Reread the second and third paragraphs on page 15. The story states:
“I don’t think you’re going to win this time” says Rosie, trying to signify with her hands on her hips all salty, completely forgetting that I have whupped her behind many times for less salt than that.
“I always win cause I’m the best” I say straight at Gretchen who is, as far as I’m concerned, the only one talking in this ventriloquist-dummy routine."
In this passage, what is the word “salt” trying to communicate?
