Answer:
Step-by-step explanation:
Boarding schools basically ripped kids away from their parents and forced them to attend boarding schools which were supposed to help them become more "civilized" and assimilate with the rest of the euro-american society. The schools taught skills that were way below the standards, and thus these kids could not function well in the society. These kids were also ripped from their homes so they did not fit well with their own society as they had little to no knowledge of their own culture. These schools were also full of sexual abuse, physical abuse, trauma, emotional abuse, and even scientific testing.
Thus, in short, these schools had extremely negative impact on native children as well as on native parents. These parents witnessed their kids getting ripped from them but could not do anything to stop it, thus suffered from emotional suffering from separation.
