New Year's is a few days away, which got me thinking about going out and naturally...dancing. Then I started thinking, man I wish I could do the nae nae like I see it online or do the sweetheart dance like I see at country concerts! I like to think I can dance, but in reality, some of these moves, I just can't get to look the right way...
