I am sure you will be meeting many people on a given day and why you have met them is because we are all members of one God’s family. And in this life we need help from each other to carry out the assignments given to us by God which is the ultimate purpose of life. And in this exercise age, caste, creed or religion do not matter. We are all interdependent in some form or other. Perhaps the person you are referring to could be a co-traveller in life like passengers in a railway cabin who have to co-exist till you reach your destination.
