• a long time without two-way communication, now he can adapt because it's expected of him
• mostly uniform "social smile" with little variation
• generally a rather uniform and seemingly distant facial expression
• social chatting only with family members, not others
• little interest in other kids his age, rarely (if at all) being the one to initiate contact

Found this in some doctors notes from a few years back, not sure if it was specifically autism related but it seems close enough :P

It's kinda funny now seeing my smile at the time being described with little variation and sometimes seeming sightly condescending. Makes me wonder how much of that was just me trying to smile at appropriate times
