This finally occurred to me the other day. NTs can just have a conversation without putting in to much effort but for us it requires concentration. Casual small talk becomes a chore so we get tired off it and try to get out of the conversation. This isn’t something NTs can understand since they don’t have to put thought into talking and acting “normal.”
The possible exception to this is when Autistic people talk about special interests. This creates dopamine in the brain so we basically become high.
The downside is that it is pretty brainless
Brainless is good, save your energy for when you’re ready to overshare about lego in 30 minutes time
Or try to remember something relevant but forgot all the details
