One of the first autistic traits I noticed in myself was that I often mistake joking for serious; not consistently, but enough that it's notable.
In addition, even when I recognize something as joking, I often find myself answering as if it were serious anyways. This makes people think I've mistaken their joking for serious even when I haven't - they point out that they were just joking, and I say "I know".
I'm not entirely sure why I answer seriously when I know someone's joking; I have two potential reasons, both of which may contribute, and there may also be reasons I haven't thought of.
1. Although on some level I know (or at least suspect) that it's a joke, another side of me doesn't actually realize it, and the part that doesn't realize it is what determines the answer.
2. I know it's a joke, but I can't think of a joke-recognizing response fast enough, while a serious response comes quickly to mind, so it's what I end up saying.
Does anyone else recognize this phenomenon?
I'd like to answer jokes as serious less, and I think it would be easier to stop responding seriously to things I know are jokes than to become better at recognizing jokes. Haven't yet figured how to do it, though.

Now convinced that I'm a bit autistic, but still unsure if I'd qualify for a diagnosis, since it causes me few problems. Apparently people who are familiar with the autism spectrum can readily spot that I'm a bit autistic, though.
