Final answer:
Aven feels betrayal and anger at being put up for adoption by Josephine, seeing it as a personal rejection and abandonment that contradicts her expectations of a parental bond.
Step-by-step explanation:
The passages reflect the complex emotions and considerations involved in the decision to distance oneself from another person, whether it be through adoption, rejection, or estrangement. The common thread is the profound sense of betrayal, loss, and sometimes anger felt by those who are left behind or put aside. These sentiments are particularly intensified when such decisions contradict societal or personal moral expectations, as seen in the outrage expressed by the characters in the excerpts.
In the context of the question, Aven likely felt mad at Josephine because putting her up for adoption might signify a rejection of Aven's existence and a shirking of parental responsibilities. This act of being given up for adoption could be perceived as a profound personal abandonment, provoking feelings of betrayal and anger, particularly if Aven had hoped for a nurturing relationship with Josephine.
