Who to be blame?

I joined the Tzu Chi Da Ai Ma ma ( a group of mothers who volunteer to school to tell/show moral stories based on Jing Si Aphorism).

One day we showed a group of standard 4 students about a story on filial piety. The story is about how a mother crow took care of young crow.When the young crow has grown up,it went to find food for its mother instead.When the jungle on fire,it rescued the mother from the fire scene,despite others discouragement.

After the performance of story,during the Q &A session. We asked a girl,how could she repay her parents when she has grown up. Her answer is 'I will go to work and send my parents to old folk homes.'

Points to ponder;

Is she wrong by giving that answer? (whereas she may just immitate from adults nearby? If we said she is wrong,is it means those who are sending their parents to old folks homes also wrong? ....
