Autism is a very serious topic that millions of people deal with on a daily basis. So many things stem from Autism, such as Anxiety, A.D.D., A.D.H.D., Etc... Some parents have it worse than others. Most of parents pray that the following day will not be as bad as the one before, or the one before that. It's impossible for an NT parent to understand what an Autism parent deals with on a daily basis. Please don't make the mistake of judging someone else's child, or their parenting; in other words, don't say what you would do if your child were acting that way. Truth is, there is no way that you could predict what you would do, because the world of autism is not a world that you know. So, there is no way. Not until your child is put in the corner because he/she would not stop hitting themselves in the privates repeatedly, a nervous reaction some have. It’s symptomatic of Autism, but disrupting the class, unknowingly, causing the other kids to laugh. Maybe wait until your child is chastised at school for making funny faces. But it’s not their fault because different nerves are stimulated, with a particular condition, or maybe the medications they take to stop the unwanted eye twitches and distorted muscular movements within their face. Wait until your child is given a bad mark in school because they could not figure out how to copy the stick figure that the teacher drew on the giant chalkboard, how to get it to fit on their piece of notebook paper. Wait until you see your lad burst out of the store restroom and ensue chase across the lobby after a shadowy figure that is not even there. Not until hundreds of hours have been spent at the kitchen table going over homework the teacher assigns, and then the extra that you make up in order to keep your aspie up with the rest of the class. Even though, it’s usually met with disappointment on report card day. Maybe after you or the coach has lifted your child from the flat ground for the fifth time because they have simply fainted because of whatever stress has manifested inside them. Think of all these things, then imagine you get to where you can deal with it, and things are going smoothly. Then your kindergartener is arrested for sexual harassment at school because they hugged a classmate, because they were obsessed with hugging. So, he/she are going into the first grade, now labeled as a sexual predator. Please try to use proper etiquette when communicating with an Aspie parent. 

Don't overly discuss how well your NT child is doing in school. Because the Aspie parent is probably not having the same luck.

Also, be careful about; even offering suggestions on what might would help, because that itself is somewhat insulting; for most, good aspie parents have already thought of and tried your suggestion. And the Aspie parent doesn't want to be rude and say that there is nothing the NT parent could say that would help. They respond with a quick:

"Yeah, alright; I'll try that." and then look down to the floor, while they wait on the subject to change. If you're in a situation like this, just let it go. Wish your aspie parent-friend well and go on with your day.
