I Do Not Speak Nonverbal: Due to the number of different species running around with radically different – and hence unrecognizable, without a lot of practice, and never instinctive – expressions and body language, it is generally a good idea to assume that no-one around you speaks nonverbal.

This is also why Eldraeic, its simplified trade pidgin, and most other commonly used interlinguae come with attitudinals as a basic language feature – and with good translators, voice of elcor abounds, as do other means of conveying one’s emotional states.  (Although, for the most part, I “edit this out” as part of Translation Convention, since I suspect most readers would find it… irritating.)
