In this short span of life, We should try to make each relationship memorable and again it may have its own disadvantage with it. We may miss someone too often as we move from one place to the other. Let them live with in us in the memory and in sooner or later part of life you may meet them and relish on the memorable moments once had.
If u hate someone in your life, u r spending too much time in making a relationship and finally hating them and thereby u r mentally disturbed.
So never hate anyone even though they do. Enjoy the life as it comes, then life will be beautiful.
