Apparently the groundskeeper at my apartment complex picked them up and put them behind the front desk with a note saying that I needed to be called---they are electronic keys so it's easy to determine which unit they belong to... that never happened. They've been missing since last Tuesday and I've been scouring my walk to school and the vet school itself for them since with no luck. I had basically given up entirely yesterday. I wrote a check for the $200 it was going to cost to replace all of the electronic apartment keys (so that doesn't even include my car keys, neuroanatomy locker key, house keys...) to take to the main office, turned it in, and received my replacements. After I got back into my apartment, my phone started ringing and it was the front desk worker who basically said "Uhmmm... looking again, I think we have your keys. They were supposed to call you last week; did they not?"
So yeah. I never bothered asking the workers at the front desk about them because I'd figured that they'd contact me if they were found since it is so easy to link them back to the owner. Nope. Guess I'll just remember to explicitly ask them upfront if I lose something else.
That's amazing.

But for real, losing your keys is so, so, so stressful. They're expensive to replace and you need them for virtually everything. It sucked so bad to not be able to drive myself to the store all of last week.
