I can be fairly spontaneous, or perhaps its just that I don't like planning. At an rate, I rarely turn down the chance to get out of the house, especially when it involves trying something new. I once knew a guy who got a flat tire and had to call a tow truck to change it, that's not me! I'm pretty hands on and prefer to do things myself.
I sometimes feel a little behind the times when it comes to this social media stuff. I tried facebook, but got board with it years ago (I was pretty hooked on farmville for a while though!) Twitter is something I've yet to try. I would definitely prefer to meet someone without involving a computer, seems a little difficult though.
