My beautiful wife is very good about the time that I spend doing martial arts. She calls me, "my trained killer" and we refer to my practice time as "honing my killer instinct." We usually pronounce it, "killer in-stink." Well, just like you can over-sharpen the edge of a knife, one can hone one's killer in-stink to too fine an edge.
The upshot of this is, no class tonight (Friday the 4th). Elise and I are taking Kristof to Natchez to see the trace and the Indian burial mounds and all that historical stuff before he has to go back to Ukraine. We'll be back to honing our killer in-stink tomorrow as usual.
