this must be another phrase they teach you in med school because i have been hearing it a lot from doctors and nurses since i approached the end of radiation: now you can put it behind you.
but when i ventured once again into walmart, this time without a hat or a scarf, with only a quarter inch of hair between my scalp and the world, a woman passed by and said, "i had a haircut like that--twenty-eight years ago. good luck!" and patted my hand.
if after twenty-eight years she still felt compelled to reach out to me, i'm not sure you ever really put it behind you. unless maybe it is like your own shadow--behind you and mostly unnoticed, but attached to you... forever.
