No... not that I've noticed.
Wait... I actually have had similiar moments. I'm usually always laughing (especially when I have nothing to add to a conversation) and recently I had to shut myself up quick, so the person wouldn't think I was laughing at him when the teacher randomly called on him in class (plus he got the answer wrong).
Then about a few months ago one classmate was going back and forth with another classmate. I was watching the exchange, laughing, only to suddenly see the other classmate wasn't laughing anymore, clearly offended. My reaction was a surprised, "oh", while the other guy apoligized, the offended one ignored us (cold shoulder).
Once I had to correct a classmate who thought I was smiling for no reason. "Nope, grimace", was my spoken response. Big presentation day, printer is being painfully slow, my dress pants are slightly too big (due to weight loss, and no belt), my jacket has caused a lint mess on my black dress shirt which I also didn't have time to iron. Oh, on top of that my group members did not email me their part of our Final Project like they were susposed to (I'm the presentor damnit). Stress...
Overall I don't think it (the topic) happens much to me.
In my new classes I have this one classmate who definitely doesn't seem neurotypical. He kinda has a stutter, his constant jokes are very crude/sarcastic (it doesn't bother me because I understand he's joking), plus he is always laughing. Very loud/obnoxious laugh, sometimes at inappropiate times...
