So, I learned about DDR last night for the first time. I mean, the phrase I heard before, but I truly had no idea what it referred to. Christina showed me this website, where you can perform the "steps" with your fingers. I quickly learned that I have some leraning to do. Based on that idea, we quickly bid on a ddr mat on ebay, not realizing that yes, the price was low, but there's $60 shipping charge. Yay! Nevertheless, check it out, it's cool.
