Pain of missing friends is realised when u r alone watching a gang of friends enjoying in front of U and U remembrng d past which u spent with ur friends!
Time and distance are not important between friends. When Friend are in the Heart, they remain there forever. You may be busy but trust me you are always remembered.
I met U as a stranger, I leave U as a friend, as long as the world stands, our friendship nv ends. All friends nv split N even if they do they will meet again.
