"You cannot always be torn in two,You will have to be one and whole for many years"
"You have so much to enjoy, and to be, and to do, Your part of the story will go on.."
Other than them who come and go, we too live our life by come and go. We leave for a good reason, or another things to explore while we come with hope. The same goes to the people who "go" to achieve their objective. Face it, there's always a good reason to come and to go even without saying goodbye. That is their part, and our part is, life goes on..
I really hate "goodbye" and prefer "see you around" to end my meeting. Smile a bit cause the last view is the view that is going to be carried on for years to come....
