I went to a special school for about a year when I was 4. My doctor had some tests done for me when I was 3, and they concluded that I had a speech and learning impediment. During my time at the school, the staff also noticed that I actively avoided playing with the other kids, but this was before AS was generally known. As it was, I managed to pick up speaking and learning within a year, so when I was five I started primary school with all the other kids.

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
