It is something that should NEVER be resorted to. And, no, it doesn't help us function, especially when those in authority side with the bullies. It destroys and tears down people, it makes it extremely difficult to reach out and trust people (especially when people you called a "friend" joins in on the bullying so they don't get bullied themselves), and instead of having fun and forming those fun memories that your supposed to in school, school becomes hell, you hate being there, and you become an anxious wreck who develops stress related health problems (even young). And, yes, it really happens that schools do dismiss it as "teasing" and say the bullied kid "over reacted," or in my case was the one who was causing trouble, when they do stand up for themselves.
