Rafi's grandpa seemed to have two rules which, when followed, made you a good dancer. Those rules were to be both fast and vigorous. Raf seems to have learnt this lesson well. Here he is dancing in Spain. Two of my sisters were staying in a hotel when we were there and to take advantage of their free wifi, we hung out in the 'entertainment' area where the next youngest person was 70, waiting for the disco to begin.
