freedom of speech?

What is freedom of speech really and does every body follow the law freedom of speech? I believe what David (from speak by: Laurie Halse Anderson) had thought about freedom of speech.

He believed that if you open some thing up to the world than you can continue the conversation with no body that you cant speak about it any more that you can say what you want when ever you want to.

While Mr.Neck believed that sense it was his class he can tell people when they can and can not continue there conversation.  David is right but it is Mr.Necks room so he needs to respect that.

David says that he continue what ever he wants but when Mr.Neck says no he means NO. To be able to follow freedom of speech Mr.Neck would have to let David speak but David should not have disobey him either.

So either way no body wins.
