I can only speak for me here, but it's something I've always done, subconsciously. I'm autistic, which explains part of it. But there's no logical reason. I don't always notice I'm doing it, but others do, I had an ex get angry at me for it. Thankfully I avoid most real life interactions these days so avoid it.
I imagine it's an evolutionary thing, but it just goes into overdrive in certain people or groups of people.

Who even wants to listen to a conversation with her? Apart from sad neckbeards I mean. FFS, is every arts event in on her grift? It's made me really mad/sad/all feelings are interchangeable.
