By the way...I didn't know you needed symptom before age 3 either, but I had them. The fact of not being able to read body-language and voice cues has been my my most frustrating thing in trying to integrate with anyone else. I used to joke with people about this one movie I had seen. It was called "Deck the Halls" or some such thing, and it was a Christmas movie, where Danny Devito told his competitive Christmas neighbor, Matthew Broderick, "is that sarcasm?!...Because you know, sarcasm flies right over my head". I never forgot that movie line, and as short as most people claim Danny Devito is, I think he and myself might be the same height, which makes the whole philosophy that much more relevant!
