Because they are incapable of following simple instructions

Haha thats like where mine is
I really want it at nipple level or a bit lower
(nipple level OUT of a bra.. I have the boobs of a 40 year old who has breast fed 3 kids... ie, my nipples are a lot lower out of a bra than in one

but who really cares!)
and hahaha yessss I totally measure my hair in relation to my boobs! ALWAYS HVE DONE... I always wanted to have my hair longer than my boobs so I could be topless and my hair could cover my boobs
