I guess it depends on what someone means by "reading the room". I've been given the impression people expect the room to read the same universally, as if there was anything inherently perceivable about the situation. It's not for a lack of trying, but I'm always graded low on that skill, often by the same people who think I phrase something as being hostile just because of my wording when I never imply that. If I feel a certain way, I say so, and I don't dishonor people because they're not in the mood to feel the mood I feel.

That said, me walking around a flock of five dozen geese at a park and getting attacked by all of them because I didn't understand they hated my presence takes the cake.
