Criticizing people, winding them up, making idiots of them or fooling them doesn’t make people with autism laugh. What makes us smile from the inside is seeing something beautiful, or a memory makes us laugh. This generally happens when there’s nobody watching us. And at night, on our own, we might burst out laughing underneath the duvet, or roar with later in an empty room … When we don’t need to think about other people or anything else, that’s when we wear our aural expressions.
