Blind parents have high expectations of their blind children just like Deaf parents of Deaf children do.
If truth be told, the expectations of a blind parent may be higher only because a blind child needs to be physically shown how to behave and perform daily living skills. (taking a bath/shower, brushing one's teeth, combing one's hair, dressing, eating, etc.)
A Deaf child, on the other hand, can learn all of these behaviors by observation.
Still, a Deaf child needs explanation on certain things. I remember that someone got upset and told the deaf person that he should know better but no one explained it to him. I can't remember what it was but apparently it is something that the kids can overheard and learn from that.
