It's annoying. Between the ways we decorate our quarters to our clothing and even where we rest at night--they want everything to be "just so," at least to an extent. Supposedly it's because Hell doesn't see us the way we see ourselves--and so, if we don't maintain our separated identities, we'll all start to blend together... and Hell will make us all into the damned.

It could, however, all be a very clever and elaborate tactic of manipulation.
