I'm not trying to be rude. But this guy(we have hung out a few times before) he has autism and asked if I would hang out with him again. Now, I don't have autism so I don't completely understand it. But the last few times(over the summer) we hung out, I found it kinda awkward... I tried to make conversation with him at times and he would just stare at the wall and look around. Does anyone have experience with people with autism so I can better understand him and be a better friend for him? Is autism like being shy or something?
