no wonder they said you fire words at people
its the same mechanism as a gun
you aim at the target
   the person
you pull the trigger
   you start yelling at someone
you feel the kick of the gun
   the instant questioning if you should have started this
the bullet hits the person
   the words hit deep and they feel the pain

and both these wounds can effect someone minorly and severely and can even be fatal to the person receiving your words or bullet
