don't ask me why

When someone asked us a question, most of us would be compelled to give an answer.  And if we didn’t have an answer, it seemed unacceptable to ourselves and others.  However, not all questions would have an answer, at least, we could not claim that we had answers to everything.  Even the brightest, smartest person would sometimes find themselves without an answer to the most common question, like, Where’s my keys, wallet, mobile phone, etc?
