sure.....

yes for what all things we do we must be sure... otherwise it need to be answered... the questions may be vague or never be mentioned... or will be haunting for that sometimes... the answers are pretty discussed but for what... that has never been thought... even if it surrounds us we may never notice it... thats the truth... which we never accepts... its not because we are hiding something... its because we need to confide ourselves or the environment... thats the significance or the implication of the word sure...
