If I deviate at all from my shower routine I cannot remember what has been washed or not. It must be hair wash, hair condition, wash arms, wash front torso, wash back torso, wash legs, wash armpits, wash front and back holes, wash feet, rinse conditioner, wash face and neck. If I don’t do things in that order for whatever reason I am lost and have to start over. God forbid I take too long a pause between feet and don’t remember which one I did already.
