He begged his parents every day for a month
Does this child have some sort of handicap?
yes, he is retarded
It sounds like the parents should be helping this kid out, judging by his condition.  Part of the role of parenting is to provide for their child!
The parents aren't at fault here.
It isn't right for a parent to dent a mentally disabled child a request, as long as it is reasonable. They should just get what their kid wants if they can.
