Let my suffering be your reasoning to thrive. Let it be today. Let this be your motivation. Clean, my sisters brothers and none of the above. Clean.
ProTip: push your knee(s) against the sink for extra support. Initially you'll feel a little weird, but you won't care after your back stops hurting. You can also use this when brushing your teeth and washing your hands.
