Superpower - Speedster

Serenade Sanctuary, Cheonma (163.758,79.2644,69.1672)

One of the questions I like to ask just about everyone to get to know them a little better is, 'If you could have any one superpower what would it be and why?'

I would want to have the power of speed. I have always been drawn to being a type of guardian so being an avatar for the positive speedforce and helping to maintain the balance between positive and negative appeals to me.
I also hate traveling in cars and would like to be able to just run anywhere super speedy fast anywhere I'd like to go.
I am... a bit anti-social so being able to run to the store get what I need and just leave the money on the counter all without being seen or having to interact with people would be awesome.
Phasing through stuff and things is just a cool bonus.
