Riddle: What is it that is deaf, dumb and blind and always tells the truth?
As we all know, mirrors, if not used in an amusement park, reflect exactly the object or the person in front of it. It is deaf because it cannot hear what you say because the person in the mirror is just your reflection.
It is also dumb because it cannot think, and it is blind because the eyes in the mirror are your eyes, not its. When we come to the always tells the truth part, we might remember Snow white’s mother from the tale. A mirror always tells the truth since, of course, it only reflects reality. The answer of this riddle is a mirror.
Answer is: A Mirror.
