I find myself bimodal, when comparing my "speed" to others in social situations.

If there's something that's novel to me, I feel like I'm slower than the average bear. Not massively slower, but with a desire to take the material aside and spend some time alone with it.

But if it's my home ground, if I've been living inside it, I find few people can keep up with me.

At least part of it is that social interaction takes a bit more processing power. I know I get a bit autistic and info dumpy when I know the ground, and that relieves the social pressure (though I know it costs me points too).
