Answer:
Ernesto was mistreated by his uncle.
Explanation:
This question corresponds to the text Banyaga: A Song of War by Charlson Ong.
Ernesto waits for his apprentice, and this person is his nephew. He did not want to accept him, but finally he does it because he does not want any child to have to go through what happened to him in the past and he remembers the mistreatment he had by his uncle when he was in that place, and who his uncle did not either wanted to accept.
