The problem is that most parents coddle their kids to much. The sad truth of the world is that life is hard, and people are dicks. I'm not trying to justify being a dick, but crying about it won't solve anything. You need to be able to shrug it off, and since nobody else (Read: parents) seems to be teaching that, I'm going to help.
Step 1: Someone calling you names? Call 'em names right back. Ask them to cause a vacuum on certain parts of your body. Attack various parts of their looks that can't be helped with names like "pizza face", "four-eyes", "turkey neck", and "huge gaping vagina".
Step 2: Make use of what you have. People calling you fat? Sit on them. I never make fun of fat people (to their face) for fear of a giant ass being the last thing I see. Too small for that? Burn down their house. Na, just kidding. But sack-taping (also called "nut-knocking") will do just fine.
Step 3: DON'T GET OFFENDED. Having a thick skin is a must because chances are, if you take it far enough, then the person that started shit will be the one that ends up crying. People are vultures that can sense weakness a mile away, so save the tears for your pillow.
Following these three (mostly serious) steps is only the beginning. It's up to YOU to decide how other people treat you, and to do that you need to be able to dish it out as well as take it.
And as far as the article goes...
HAHAHAHAHAHAHAHA!
