Also there's a lot of difference (for me anyway) between dancing when you know (roughly!) what you're supposed to do, like barn dance / ceilidhs, cajun or morris, even easy to improvise in those situations - quite happy to make an idiot of myself, love it, but I can't for the life of me get up to dance to disco / rock. Bum frozen to seat, face red, make up excuses about bad ankles... actually the last time I danced Cajun I did break one!
