When you completely know the person sit next to you cant understand  what you are going through, silence is the best tool you can used than increasing your frustration to more depression.people  thinks talking helps but some times talking is not the solution, when the opinions of ones point of view can not be the reality of the suffering  person.. people stay away because  they know the person they wil get help is not you.. so keep distance than complicating the poor souls with what u think is better for them, cz definitely  you r not gone through their life. Advices any can give.. but give only when asked!there are situations when a pat on the shoulder or a hug gives the intimacy  for relief, than you open your bag of advices..., that too if the needy person welcomes u only ! Understand  every one is fighting their own battles, their life is not a cup of tea for u to judge.
