hair we are again

last year, it was off with the hair. this year it's back to blonde. i was recently told for the very first time in my life that i look nothing like my sisters. what? then it was, "maybe bacause they are blonde..." double what? i've been blonde my whole life, natural or otherwise, with brief dalliances with red and different shades of brown. the past 18 months i've been more of a dark blonde, okay, brown with blond highlights, but now i'm back to my roots. or rather, the bleach...what's with a woman and her hair?
