Thank you, The Lonely Traveler, Thebubblemouth, bhikhaari, pyaaronepal, and dukhe for you input. I am glad there are others who think the way I think. Also, thank you, Bhojpure01 that you have raised a serious concern. Surely, you are true in every words. That is the reason we have to make ourselves ready for doing something ourselves and go back. There are hurdles to which we have to find solutions for.
