Some autistic people are very good at certain things.
They are better at these things than almost anyone else.
For example, they might know the day of the week of any day in history.
Maybe they can draw a city perfectly from memory.
They might be able to do very hard math in their heads.
Most autistic people are not this way.
We are good at some things and bad at some things.
But it is very rare to be the best at something.
