I had one on Monday
sometimes its not you, you might just get a bad run of 4-5 poor leads
it happens. You won't realise, till you've been dancing a bit longer, who's good and who's poor. Don't alway's asume it's you.
Sometimes there's just something missing from the atmosphere, they haven't played a track that's particularly inspired you and unfortunately, sometimes you look round and think to yourself, Oh my god, there's no one here I really want to dance with!
I ended up going home early, fed up. I felt that was the better option than sitting there, fed up
After paying £7 each for me and my daughter, it was a bit depressing!
BUT THEN, On Wednesday I had one of the BEST nights EVER! 
So yes, we all have OFF nights!
