Speech edits

Why did obama make the edits to his speech you ask? one simple answer to make it better obviously. honestly i dont know why he did it maybe he just didnt think of some of the things in the speech the first time he wrote it. i do that sometimes too, find a place where i add more onto in a paper or a speech of mine. But i just think Obama wasnt pleased in his writing when he was finished writting it the first time around and he decided to make it better. i feel as if he changed it to make it a more personable speech toward teddy. but i really dont know why he changed his speech, but honestly who writes something one time and doesnt change a single thing about what they wrote. I mean he is the president but he isnt some sort of writing machine. he's just like everyone else, just makin things better one sentence at a time.
