What your mind perceives and eyes see may not necessarily be the case all the time. Life is strange and at times carries some unbelievable than what one would normally imagine or accept ...!!
It may perhaps take only a moment to have crush on someone, an hour to like and a day to develop affection & love ... but it takes a span of life to forget one ...!!!
Yet for a human being nothing is as essential as endeavor to live with the present ... and to live with a cause, because one cannot amend past and one cannot foresee future.
