Sorry your DS is having such a hard time, Lisa, and I'm also sorry I don't have anything helpful to say--just that I sympathize, because I can totally see our DD having similar difficulties in a few years. It sounds like you're handling it as well as anyone could, really, and better than I would. Also I would hope the teacher would realize at some point that regardless of any particular kid's idiosyncrasies, it doesn't seem like a very good idea to pass something around the classroom that, if anything happens to it, you're going to end up calling the police. I imagine he meant well and was just trying to give the kids some exposure to an element or something, but passing it around just seems like asking for trouble. I'm hoping things go better for everyone in the future.

Best of luck!
