My natural tendency in social situations is to process things rather thoroughly, which is more work but tends to lead to a better understanding of what's going on (modulo the fact that some kinds of interactions don't make sense to me and thus are nearly impossible to integrate into my model). I could, in theory, rearrange my habits so that I was able to interact for longer stretches without getting tired, but at the cost of some of my perceptiveness, and I'm not interested in doing that.
