How do my arms and hands know
to type no further?

Crack. Thru. This. No further.

Almost like cramps. The resistance.
Muscle's reluctance decorates
these lines

Working my hands til fingers push on. Stretching
between lines.

This is not [clenching] bad

Look at your hands.  Stretch them.
Clench a fist.

I'm smitten. I am hardened. I am flicked.

A fingers width to meaning.  This is mine.

A note we all like.  Playing.
