Lost presence of mind

Trying to finish up a job
Had to cut out big sections  
Of the floor to get under the house  
To repair the floor trusses  
And replace the screw Jacks that also  
Support this floor  
Upon starting today I was bringing in  
Plywood to cut and put down
Not paying attention to the holes as my mind was elsewhere  
I set the piece of plywood upon two wooden horses so it could be cut
Just as I was turning around...and...
My mind still deciding to be elsewhere  
My left foot decided to fall through the hole.. that was directly behind me ... and my thoughtful mind not helping me at that moment... almost like a clip out of a cartoon ... down I went.. now I'm no acrobat .. nor have I been practicing my splits... but split I did... my right foot decided to try and stay upright .. and yes... my mind still elsewhere. .. SNAP...went my right ankle. . Almost like a chicken bone being cracked.. actually it might have been a little louder .. fun times.. when I'm not paying attention.
