IDK

 These have become my three favorite letters in the English language. They are relaxing letters.They stand for I Don't Know. When someone texts me with questions that I do not want to embellish on, I respond, IDK. There are no follow up questions. When I am asked a question face to face, I respond, 'I don't know". Again, no follow up questions. No excuses, no rationalizations. Done deal. IDK is the equivalent of "diarrhea". No one ever questions that either.
