I could smell your experience through your description with help from flash backs to my own escapades with rodents and hideous neglected government buildings.
I had a power socket in my bedroom as a kid. I couldn't use it. Every time I tried it would stink. We had a terrible rat problem at one time. One of them must have died in the wall cavity. I think I baked it if I used the power point. 😷😖🙊
Oh I can understand all to well! We've had a couple die in the roof before too. The smell feels like a physical assault!
