How can I assist you at this moment?
assistant
 Actually I am an old person and I don't know how to modify a flight ticket that is booked by my son in the last week but suddenly I got admitted in hospital with a typhoid fever, so I am unable to travel the trip and my son is busy in his office work. Can you please help me in changing my flight ticket?
user
Sure Paul Walker, I will help you with that.
assistant
Thank you for your positive response.
user
Please wait a moment to check flight availability.
assistant
Sure.

Sorry Paul Walker, no reservation has found under your name to change.
