So uh, there was a noise in the kitchen. I've been hearing it quite often lately at night, dishes bumping together, and I thought maybe it was the dishes on the rack, or something shifting because the building shakes occasionally. The kitchen lights were on and I was at my desk, so I looked over... yup, big grey rat climbing out of the sink.
Glad it's not a roach, because then I'd actually be scared. Right now I'm just thoroughly grossed out and ticked off that I'm paying $600 a month and not only have rodents in my walls and cupboards but now in my sink as well!
