Everyone is special, with his own and unique way.You might be fat or slim, genius or idiot, strong or weak but you are still unique and nobody can say that you are not.Despite, if we were all the same, the world would be boring, wouldn't it?Just imagine: A world full of men with black suits and women with pink blouses and white skirts, it sucks, doesn't it?That's only one of the billion scenarios, because as we said everyone is diffrent from the οther.But some people like the way they are and are annoyed when the other around them staring at them with a look full of critisism.
Ok, lets get it the other way around.Imagine yourself(if you are not) be the one who is being teased by the others, you hate it and what are you going to do next?You will do what they did to you, but to some other kid and that kid to the next.Where does this lead to?To a place where everyone looks the other with suspiciousness, aggressive characters will be born this way and no-one will accept the other if it has not the same aggressive and dark soul.
To sum up, what I want to say is that making fun of everyone who's different won't lead you nowhere.You'll have just enjoyed yourself for some minutes( probably everyday) .Then we will all be able to congratulate you for what you've done and the "special" kid which will be "different" from you.Nothing will help later, if you need to do sth, is to stop doing it.
