Ugh. Even though it is quite cold, I have opened the patio door a bit. Can smell that burnt toast smell again. I am thinking it must be coming from something someone on my floor is doing, but I certainly have not been able to figure out from where or who. The odd part is that the section of my apartment where the smell is strongest is nowhere near a door or window or air vent - nor any type of appliance, heating or electrical equipment. Or anything that would cause odour (since it is the space right in front of my shelves of stamps). Most odd.
And the smell usually appears suddenly & quite strongly for a short while, then fades away.
