Online self is extrovert, mostly because the winnowing of the senses down to a few allows me greater focus for my ADHD ass. Or Autistic or whatever it is.
What you see on line is me with a moment to think. Real life sometimes comes at me too quickly and my responses are often of the “woah hold up wait a sec let me process this” variety which can come out in a few verbal words, or body language, things unnecessary online.
The give and take of real world conversation can be tough for me to navigate. It’s short and punchy, or it’s long and drawn out. Being over half-deaf listening is tricky because I don’t hear every word or most really so I figure out what’s being said “in context”, so it’s a constant concept-building exercise, which can be taxing.
So any personality differences are due to limitations in real life that aren’t present online.
Well, I feel normal. I feel myself. Offline, it’s a constant real-time negotiation of meaning combined with a tug of war for power. Not always but often, enough to be frustrating.
