This is a very interesting blog about a group of people that has traditionally been neglected by society.
"She just sits there emotionless for an entire 90 minutes, staring into the abyss, never volunteering to speak or do anything."
That sounds like a good description of my public school years. No one ever stopped to think "maybe the student has severe A.D.D. and can't concentrate"- instead they think "why wont they do what I want?!" No teacher ever showed concern or empathy toward me when I couldn't stay awake, it was always "everyone has to do more homework if he falls asleep again," a joke, or ignored.
The teacher failed to engage her students and instead of thinking about changing her own behavior/teaching techniques she is like a child trying to pound a triangle-shaped block into a star-shaped hole.
