I got this information from an autistic person on Twitter who posts useful advice for other autists. She says:
I may be wrong, but... I think I finally figured out that the questions, "Are you doing anything fun for the weekend?" and the same questions framed in past-tense, are social cues that just mean: "I'm fishing for a small talk subject. What's exciting for you recently?"
Which means, even if you don't have something to talk about that fits *exactly* what someone is asking, it's generally okay to respond with: "No, BUT!"
Examples:
Q: Got anything fun planned for today? A: Not today, BUT in a few days I'll be getting a game that I'm looking forward to playing!
Q: Did you travel anywhere over the holiday? A: No, BUT I was able to experiment with cooking a lot, and I made some new foods I like.
Basically, these questions are a social script where they're trying to find a subject that the person wants to talk about, that also isn't boring for them. So they cast a wide net, with a question that's "safe" that probably, hopefully has an answer.
But whether they realize it or not, I think the majority of the time, the *intention* is just to get a conversation started, for reasons from literally getting to know you, to trying to be polite and making the other person feel more comfortable/at ease by showing friendliness.
And in my experience, the majority of the time, if you respond to a small-talk-prompt like that with a "no, BUT," most people will roll with it, because it gives the conversation *some* kind of hook to work with. As opposed to: Q: Doing anything fun this weekend? A: Hm... nope.
Granted, I'm also autistic so I might be missing bits and pieces of this! But this is at least what I've pieced together for myself so far.
"No-but" is a cousin to "Yes-and".
^This has helped me a lot! A lightbulb switched on!
I often get asked what I'm doing this weekend/ what I did last weekend and I just say, 'nothing.' or similar.
So...the people asking this want to start a conversation! They aren't just being nosy/annoying!
I hope this helps some other people on WP too!
