Well then John We've got that established.

Consider me your guardian angel. I'm your guide as soon as we get going, and I'll be around quite a bit. Are we friends, are we really good friends, or are we REALLY good friends. I guess that kind of depends on how you swing, so let's get me figured out and then we'll get you figured out the rest of the way and the rest of the story will be through your eyes.

So, what am I?
