One thing that really confuses me is when someone is looking straight ahead and smiling. I've seen that a lot and I don't know what it means or what they are smiling at or if it has anything at all to do with me or something they are thinking about or what. I have no clue. I see one lady that does that but I don't know if she does this all the time, with others, because I only saw her twice for about a minute of smiling each time, but, she had the same smile each time and I remember it vividly because I wondered what it meant and if it had anything to do with me. Usually when I see the "smiling at nothing" I pretend like it doesn't have anything to do with me and ignore it even if I think it does because if I convince myself it does I will get aggravated by it.
So much for the smile @ nothing.
Now, onto the laughter...if there is laughter, a look at me, more laughter, a look down corresponding with the toning down of the laughter to a smirk, I assume they are laughing at me, especially if it's two or more people and one looks at me and the others look like they are stifling the desire to look my way and their faces look all tense and stuff. Then I get paranoid and think they are all laughing at me in a way that's ridiculing and that sometimes pisses me off, depends on my mood.
If I say nothing and they look at me laugh, look down, then smirk I assume it's at me. Yes, I get laughed at a lot so I have the routine down pat.
If they laugh after something I said it's probably them laughing with me if I laugh too, or it can be them laughing at something I said which is sorta like them laughing at me.
I feel, a lot of the time, normal people have more control over the situation than I do.
So, the truth is, I often cannot tell exactly what people are laughing at unless they make it very obvious and when I've asked before I have gotten replies like "oh, nothing" so, that could mean they are laughing at me. I don't know if people without AS can tell or not but I bet they can.
