In social situations, I find myself changing my personality to reflect whatever person I’m interacting with, thus resulting in a (usually) mistaken assumption that I’m just like them. When I’m not. I tend to observe people from a distance for a while to gauge their personalities before actually talking to them, so I know what kind of humor they prefer or their book preferences. Would that count as dissembling? It’s something that I’ve always done naturally, but it’s so draining too.
