No port in a storm

My son is partway through his second summer at a mainstream camp, and interestingly, for the second year, the only kid he's having any trouble with is another child with special needs. Shouldn't there be some sort of honor among the neurologically impaired, that when they're a minority among the neurologically sound they bond together? The only thing I can figure is that the "regular" kids are better able to appreciate that my guy's a little different and adjust their own behavior to accommodate his, while other kids with differences are too locked into their own rigid habits to do so. It makes me wonder about the fact that I'm so adament about him being in a self-contained class in school -- would he do better socially, somehow, in a mainstream class? Or would extended exposure to him in situations where his quirks aren't so amusing cause the mainstream kids to lose their good will. We're not likely to find out soon, since I still think he needs the structure and protection that a self-contained class affords him. But it sure bears some thinking about.
