There are sometimes long pauses before my response or even mid-speech, during which I’m thinking about what’s said. But the delay is often interpreted as a cue for someone else to respond or change the subject, which often leads to not being able to say anything that i’ve spent so much glutamate to process.
I used to say “one moment” every 5 seconds while I think, but that was distracting.
Sometimes, I do this thing with my eyes jumping them around as if I’m reading a book; that gives people something to look at while they wait, like a spinner indicator.
