Lack of awareness. Many still don't understand what autism is, including me, until my girlfriend asked me to read the symptoms because I have difficulty dealing with someone with mild autism in my workplace, and I thought it was a strange behavior he was having, until I learned he actually has autism. 

We can read about autism behavior on Google because international awareness has made it more common. It's unfortunate that Malaysia hasn't made significant efforts to diagnose autism. 

He is not antisocial but super lazy. Laugh when it's not funny, cause the awkward situation. Repeat the same thing again and again, which is super annoying.

I believe different people have different symptoms. 

It's like a normal person until he speaks. But muka ada macam sedikit cacat.
