Having witnessed ds recently on a zip wire I thought that it was a perfect example of how his autism affects him.
I thought he was scared of the thing but actually, when empty he used it over and over. It was the social aspect that scared him.
There are so many unwritten rules. When you have a go you are supposed to then get off and hand it back to the person whose turn it is next, but how do you know who that is?
It is the person stepping forward, making meaningful eye contact, perhaps with their arm out. You have to judge how close to get to them, and ensure that they have grasped it before you let go yourself.
Then you have to go and queue for your turn, except there isn't a queue because it is just a platform with children huddled on it. How do you know who is before you? How do you know who the last person is currently to ensure you go after them. The other children are all doing elbowing and glancing and non-verbally stating their territory.
Should you figure out how many children are before you, you have to try and remember which ones. What happens when someone new joins the queue? How do you ensure that they know you are the last one so far and that they should take their place after you? How do you make it clear to them that they need to allow you to go before them if they either a)make a mistake, or b)deliberately try and push in front?
You could perhaps instead of point things out, use it as an exercise to get the kids to give as many examples of likely difficulties in that or similar social scenarios?
