School can be very tedious and frustrating for those of us who are SPs. I never wanted to tell my parents how tedious and frustrating and just plain boring school was because I didn't want to hurt their feelings. I would just go to school and sit there and look longingly out the window and not pay a whole lot of attention to the teacher, whom I couldn't understand anyway because I couldn't tune out any of the background noise, even the hum of the electricity (I have an auditory processing problem but that was undiagnosed until I was in my 30s). I liked art and music the best and could hardly wait to draw and paint and sing but we didn't do that anywhere enough in school..
It was very stressful to experience that, day after day. I couldn't see an end to that tedium. Sometimes, I would go home and just start to cry. My mom asked me what was wrong, and I didn't have the words to tell her.
When I was in ninth grade, I had a great history teacher. We were supposed to study China and India. The teacher gave us novels to read instead of textbooks. The novels made China and India feel real to me. I really liked the story telling and I was fascinated by the differentness of the Chinese and Indian cultures.
An inspiring teacher can do wonders for students.
I hope that your son is blessed with an inspiring teacher, who can connect with him in the way that my ninth grade history teacher connected with me.
Best of luck to you and your son.
