   # I tend to store attributes like `status` or `role` as underscored strings (a string that
   # would be suitable for a method/variable name) sometimes a simple .humanize will do the
   # trick when it comes to displaying that value in the UI user but other times you need to
   # customize them a bit which is one reason I18n is great. This helps automate the usage of
   # I18n for such a purpose.
