1. patience - if you are struggling for dancers do keep plugging away until someone gets up, then keep on going until you get enough. The best callers have done this when I would have been long gone on my way home.
2. tolerance - of novices, children and those who've had too much to sup
3. good humour - if they really WON'T get up don't get nasty (and we've seen that happen) just say "well if you won't get up you'll just have to listen to this awful band play!"

(Note to OlgaJ - Mo IS a very good caller! We love you, Mo x)
