in 15 or so years of drug use, i've never lost a single thing.
my girlfriend, however, manages to lose pills like no other... just this year, 2010, i'd estimate she's lost 15-20 individual pills (usually 1-4 at a time, so probably six or seven incidents). just a couple of weekends ago, she decides to go through her purse in a hotel lobby bathroom whilst urinating (looking for a cellphone or cc or something) and doesn't notice the folded piece of paper with her last three roxis in it spill onto the floor (at least this is our best guess as to what happened).
if she wasn't obviously in w/d and pissed/crying each time, i would suspect her of using them and not sharing then claiming she lost them just to cut me out, except she:
a) is obviously still in w/d
b) looses everything constantly. cell phone, cell phone charger, keys, clothes, books, the list goes on...
