Appointment or Disappointment

A person telephoned me and asked me””Will be available on April 3 rd 2018?I want to consult you.I have to book my tickets.  I replied “I am not sure. It depends on my Creator. Onward and return is a round trip scheduled by the Creator and Lord Yama is incharge of the departure date. Yama neither cancels or prepones or postpones our departure “.Immediately he asked me”Can you guarantee your availability?””” I replied “”It is simple. If both of us are available on April 3rd we shall meet. If I have already left by Yamadharaja Airlines you can consult another doctor. If you are destined to leave on that date neither you or I have a problem. 
Moral: We cannot give a guarantee for our life . Death is certain but it is uncertain when,how and where it will occur.
