It is really frustrating when you think you've got something. My instructor had given us what she called a little "routiney thing" with basic steps and she said when you get comfortable with it start adding some shoulder shimmies on the grapevine one direction and then hip shimmies coming back. Well I thought I could do the grapevine with shoulder shimmy, seems simple, but she had also told us to use our bodies with the grapevine and not just the feet and I realized when I did the shoulder shimmy I'm not using my body to move in the steps...grrr...thought I had that one, now I got get that and the hip shimmy.
