For reasons no one may ever understand, God decided it would be helpful for people to be different instead of the same, if only because it would slow them down a little bit. God decided it would be good for them to have to stop on a regular basis and say, 'Could you say that a different way, please? I don't understand what you mean' or 'Can you show me with your hands?' God decided it would be good for them to stop taking their communication for granted and work a little harder at trying to understand each other.
