Well, kudos for not giving up and having fun. I'm a bulgarian and ever since I was a small kid my family, especially my sister, have tried to teach me all kinds of horo. And failed. Miserably. I even took classes at some point in my childhood to prepare for the wedding of my uncle. I tried and tried, but just couldn't coordinate my feet, nor did I really feel the beats. A few years later my ex-girlfriend, which was pretty amazing at bulgiaran dances gave me lessons for a few hours. And although being a very patient person, she just couldn't stand my "dancing". As she put it it was like trying to talk to a brick wall. -_-
Take my responce as encourgement, since there are a lot of bulgarian people like me, that could not perform even close to how well you are doing (based on the videos in the other blog posts).
