Communication is the only way us humans can get together and share stuff.
Whether that is emotional or physical it goes without saying that is we fail at this really basic level then we may as well give up and hiss under the stairs.
We all know that certain professions have been led to think that having a strange outlook on communicating is acceptable but I would hazard a guess that this is pretty self generated. A case of the shy convincing the shy. In a business environment getting your idea across in as unambiguous manner as possible is fundamental to getting the job done.
