Why does my 9 yr old wander NOW?

I wish that I can find someone even here in cyberworld who has an aspberger kid and that can explain to me why we have this newer issue of wandering.....you tell him to sit here, turn around and he is gone with a logical reason in his mind. You cant discuss this with a typical mom.....I have AWESOME AMAZING friends here that love Dylan. And it does take a village to raise a child and here in Campbellsvile it is a great village....but I wish there was a mom that can think outside the box amd help me......
