Let us take the question

Questions came without any introduction. You cannot ask them to wait. They did come suddenly, you cannot claim any informations. Questions never come when you are really prepared. In case you are prepared, the question you are waiting will never visit. The question you have been waiting will never come up. The one that comes up is not even identifiable, no introduction,no notice but one has to answer the question, reply it satisfactorily. That is the order of life. You cannot take another step without answering the question first.

And the answer? Known to none!

Each question has only one unique answer and you have to take your chance. not even the wisest of all, always succeeded.
