Is it hidden? Is it safe?

Over the past three weeks, I've somehow lost some of my stuff. I'm pretty sure my 6GB flash drive is somewhere amongst the random piles in my place, but two of my rings are missing. I have this nagging suspicion in the back of my mind that some hairy-footed short people are sneaking into my home and stealing them, but that's just nonsense.

No, I haven't checked my oven.
