Can I save your number?🤣

I got a What’s up message from an unknown number. I immediately replied”Please identify yourself . I do not know who you are though I am still struggling to know who am I.”He immediately texted “I am Mr ……. and please save my new number.”I immediately replied “I have been a ? Doctor for the last 35 years and must confess to you that I have not saved anybody including you. If this is my handicap how do you expect me to save your number.” He replied “You are a Doctor and you save lives”. I  replied “I cannot help you since it is your wrong perception. I am only playing the role of a Doctor in the  the drama titled LIFE and you are also playing the role of a patient.”I am yet to hear from him.after this reply.
