It's hard to believe I posted that only six days ago!! Due to Chrimbo there've been quite a few social occasions since then. Apart from his works do, nothing very heavy and nothing with people he doesn't know. I have noticed though that he's really putting effort into always at least saying something, with close friend it's almost been a small conversation.
It's odd to watch, he goes to speak and if someone else talks or looks away he just stops - but I notice him going for a second, third or fourth attempt until he's at least said something. I know he's fighting this pretty hard. I think partly to avoid HAVING to go and get some help. Blinkin' mule!!
Thanks for all the input, it helps me lots to try and understand - it really makes my patience grow, and helps me to listen more carefully when he's talking to me about this kind of thing.
