sometimes

sometimes your head hurts, your vision blurs, you can't stand up
sometimes you're too tired, too cranky, too busy, too lazy
sometimes other obligations conflict, or you are out of town
sometimes you forget or lose track of time, maybe you sleep in
sometimes you're body aches and pleads with you to rest
but then, other times you are present, you are ready
you walk in the door, bow, suit up into your dirty gi and
it all comes together
