Certain things run in M's biological families. Massive ADHD, f'r instance. Some other stuff. We look at him -- his need for strict routines, his sensitivity to sounds, his difficulty switching tasks, his emotional spiral when thwarted, his full-body-banging tantrums -- and we are very happy we are homeschooling him. Because while I am reasonably certain that M has nothing diagnoseable, he's on the edge for a number of traits considered pathologies by the public education system.

So, sympathy.
