Life is not simple...rather its difficult when???

CCD ( cafe coffee day ) is a good place to hang around if your pocket is little heavy..... me and my friend were having good discussion on our professional and personal life.... and she said one line "today we are sitting here and talking very nicely , may be tomorrow you or me may say 'get lost ' to each other ,  what will you do ??" i mean she has a valid point........ we usually become addicted of somebody's company that we sometimes forget that everything is not permanent...... i know don't know what we actually miss about to whom which we have lost or gonna loose?? ......... but in my opinion ...rather than missing the person we miss the idea of him/her....or if i have to rephrase it...its like we miss the good moments which we spent with him\her\them.....its quite difficult to forget someone (in case you were attached emotionally) but we must understand this is the part of the life....people come and go...... but we can not stop for anyone...i mean anyone......life goes on...
