baking powder and bacon fat

I've been looking everywhere for my baking powder the past day or two, and after searching through the communal shelves and my housemates' shelves, and other places where it isn't supposed to be, I found it behind the corn starch and the masa flour, about three inches from where it usually is. Oops, my bad.

But it got me thinking about my strange habit of hiding ingredients, particularly those often in high demand (olive oil, milk, butter, chocolate). It started in my first house in college, when I had 8 or 9 other housemates (plus significant others, plus couch-hoppers, plus the occasional rasta) and hiding certain foods meant that maybe I could eat it before it all disappeared. It wasn't a horrendously huge lets-call-a-house-meeting issue, it was just a little more thrifty to put your eggs at the bottom of the pile, and place the olive oil behind the hot sauce, where it wouldn't catch anyone's eye.
Certain housemates were bigger offenders than others; I didn't take issue with the occasional borrowing of milk to make white russians, or the tomatoes that went into the pasta sauce that was served for a house meal. But there are always those people who never find the time to go grocery shopping and have never bothered to buy basic essentials, because they're readily available elsewhere in the house. And really, borrowing a little butter isn't a big deal until it's 5 or 6 people doing it every day.
So it was rather gratifying when, one day, one of my less particular roomies came pounding frantically up the stairs, asking me what it was that I had in the little honey jar on my shelf. I had made some ghee (clarified butter) earlier in the month, and it keeps well outside of the fridge, so I had put it in an empty jar and placed it on my shelf. My housemate and several friends had made some tea, and, assuming that honey jars containe honey, had placed a large dollop in the pot. But honey is not usually greasy, and being vegetarians, they freaked out and assumed that they had just defiled their tea with bacon fat.
It was a good laugh, all around.

In my current household the only fatality is chocolate chips, which vanish with astonishing regularity when one certain dude is home.
