TwinkleToes,

My son is like that. He's not Aspergers. And sorry to tell you again - DS is 7 and STILL like that frown. Actually, he's got a running parallel universe that been going on for 3 years now, and it's a mirror of our universe complete with social injustice, economic crisis, black holes, and anything you can think of. He's not interested in telling anyone else about his obsession - just me. This world is very real to him, and yes, he's extremely persistent in telling me. Even DH doesn't get the full on treatment. It's been tough on me, and I've snapped at him before (meltdown on my part), but it hasn't stopped him. Guess I've gotten used to it and am starting to think that when it does stop, I'll miss it.
