Play Star Trek Adventures with friends. Last time I got embarrassed because I couldn't think of what my character would do in a certain situation. While I was thinking the others were waiting.
I don't think about autism much most of the time but this was an autistic problem. Lack of imagination. Inability to pretend play. I couldn't do it as a kid and I still can't do it today.
I know other autistics have vivid imaginations (including Kayleigh) and it bugs me that I didn't get this too.
