Erhm, "normal" means complying to the expectation of the biggest norm that is present, and enforced...
Soo, yeah, normal is very much a thing...
But, as you may expect, "acting normal" at work, means something else than "acting normal" at a furcon. Because diffirent norms are applicable.
Imagine going to work, and starting to hug everybody there, even though that's exactly what the average person does at a furcon.
However, it's normal at a furcon, but not at work...
