Three words, but it all brings the same meaning. All of us had criticize, insult and affront before. There are reasons why people criticize one another. Some criticizes because they have a poor self image. They feel that by making others look bad they themselves look better. Running others down makes them feel important. This of course is a bad case of self deception. Others may criticize because they are self righteous. Another reason people criticize is because they are jealous or just holding a grudge. This is their way of getting even and satisfying their resentment and jealousy. Another group of people who critique are those who do it by habit. They are too used to criticizing people.

But, have it ever slipped your mind how the other party will feel when you insult them? Just by saying 'Eh, you're black. I bet we'll only see your teeth when it comes to night time!" or etc, it will offend them. Yes, maybe they'll laugh along with you and will go to the extent of agree-ing, but deep inside, you won't exactly know how they feel. And as a result of this, it'd affect their self-esteem. Maybe even before you insult them, they've low self-esteem. But why must you make it worst? Maybe it's better if you just keep the comments to yourself.

If it's already a habit, then try to control. Not every human being can accept criticisms.
