Antonio ,hung on for dear life onto a tree

Antonio ,hung on for dear life onto a tree branch, as the meandering river travelled downstream.At the end of this river was a large waterfall.

Along the river came a halting Arwen. And a stone's throw were the wraiths. She shouted the spell of the elves "Bringeth surge of water forth from Antonio!"

There was a slight trickle in the river. A naiad approached Arwen's raft. "Antonio couldn't make it, I'm Beth, how can I help you?" The ring wraiths encroached further.

I was there when it happened.

All of it. Everytime something important happened I was there. Can you guess what I am? Hint:

I am not "like Darth Vadar". I am just misunderstood.

But, like Darth Vader, I am misunderstood. So, you're the psychiatrist, you tell me whether my proclivities

will be sucked in your ball of swirly gravity stuff... And there goes Darth Vader, I feel like I'm being pulled too! My beautiful mind cannot escape! I have so much to think for!

I had received that day on my Smart Car, while I talked on my Smart phone how dumb was that!!
