I really need to be more alert when in conversations, but sometimes I just have a knee-jerk reaction of "yes" or "indeed" or some affirmation when someone pauses, and that can REALLY SUCK when the person wants you to disagree with them (usually when they're putting themselves down). I'm not even asking for help here (though it's happened to me twice in the past month and both times I felt horrible). (More parentheses: If you have a way to prevent oneself from doing this, DO TELL ME but I don't think it's easily fixed.) I mostly just wanted to ask if anyone else gets this happening to them. Share your embarrassing stories. Whine. Go eat a candy bar, then brush your teeth. You have total freedom in how you react and respond to this, even if it's just a playful response such as "Yes, you need to be more alert, you idiot. Oh, wait, I wasn't paying enough attention, uh, you're, uh... nice. Yeah."
By the way it's not that I think it's an Aspie thing necessarily; I understand that people want to be contradicted; I've just had these weird slips where I was paying attention, not spacing. Maybe it's because when I AM focusing there is usually a mental reverberation where I'm not just absorbing information but also processing and associating it, and this means that while I am paying attention, I am not necessarily in the same place mentally as the conversation is temporally. I'll get there, but not perfectly timed.
