Criticism.

There are some people who just love to criticize the efforts put in by others. Its one thing to falsely praise others.....but then its even worse to disregard good work.....and instead criticize that person for a single shortcoming and overlook the positive side of his story. A person who always gives out negative and discouraging flak is a pain in the neck and a reason for someones unhappiness. There are some who might argue that constructive criticism helps.....true, but then constructive criticism should come after words of encouragement and appreciation.
