Totally agree with you and actually kind of saw it last night at my study group.

This kid doesn't have a disability, he is just friggen lazy as the day is long. He sits there during class messing around on the computer not paying attention. Then shows up to the study session wanting us to teach him basically everything we have gone over so far. So the rest of us have been done with a question for 5 minutes and he still doesn't comprehend what is going on. So after 3 hours we got done with maybe 1.5 hours of actual work. So I just left. I don't have patience to deal with someone who feels like they are entitled to education without putting forth the work. And I bet you the other mentally disabled kids do just fine with a little extra help. I bet none of them throw tantrums and actually WANT to get an education.

This may sound a little mean also but I do feel like sometimes when people are raised with a disability, people baby them. So they have this feeling like they are just too special for everyone else. Like I know this kid with epilepsy and his parents knew since he was little and babied him and he throws tantrums and things like what you describe. I just found out after 23 years that I have epilepsy and don't do any of that what so ever. Just seems a little off to me and I think some of this falls on the teachers AND the parents.
