Final answer:
The information provided does not directly address how Penelope treats Junior on his second day at Reardon, nor does it pertain to the parent-child dynamics inquired about in the additional context.
Step-by-step explanation:
The texts provided seem to describe different interactions between characters, potentially from a novel or collection of stories, rather than information on how Penelope treats Junior on his second day at Reardon from 'The Absolutely True Diary of a Part-Time Indian'. Without context directly from the book, I cannot accurately provide an answer to the student's question. Additionally, the references made do not appear to directly address how parental treatment varies between sons and daughters or the response from children to such treatment.
