In a quiet moment

In some ways blues dancing is a lot like seining in a marsh.
Seining is a type of fishing that requires two people each wearing rubber overalls up to their armpits and holding the end of a long sheet of netting to drag said netting in a circle so that fish are forced to swim into the net and be caught.
Blues dancing is a form of social dance that emphasizes the connection between two people. Blues draws from the most basic beat of the music usually to move in very close contact with another person.
One of the first things I learned about blues is to pay attention to the space between the steps. Never pick your foot up with the intention of putting it back down again, always just pick your foot up. Be mindful of the way you sink into your foot that is left on the ground. Be mindful of the multitude of places your foot could go. Engage your abs and remain balanced and when you're finally ready to place your foot in a spot you've carefully chosen, only then should you take your next step.
I certainly don't reccomend this philosophy for all things in life but for seining it's certainly useful. In huge rubber boots in waist or chest high water where the bottom is obscured by dark muck the next step always warrants careful examination. When you're unsure of your own footing it pays to find your center of gravity.  Feel the ground gently before you put any weight onto it.  Investigate each step as an individual and significant choice.
The other thing seining and blues have in common is that they're both hell on knees.
