lines in the sand

I draw a line
in the sand.
then move the line
another foot back.
I draw another line.
make another proclamation,
another demand.
it doesn't matter.
i'm ineffectual when it
comes to lines,
to ultimatums
and promises.
and now i'm out of sand.
out of sticks with which
to move it
in a straight line.
now I stick my head into
the sand, and hope
for the best.
