At times maybe we are too critical of others without really stopping to think why. What is it about that person, or the action that person has done to warrant criticism? Is it envy that causes us to speak with a bad tongue? or is it because we do not like them, or they us.
There are many reasons why, that we within ourselves spit out criticism of another, it may be an inferiority of own hidden deep within us. Think before you speak, ask yourself why? before you speak.
Remember, Criticism can be constructive, but said wrongly or for the wrong reason can be extremely destructive.
