Here's what I think is happening;
The guy who lives across from me comes home every night and makes a meatloaf. His apartment, being a mirror-image of mine, is small and heats up quickly when the oven runs. Because of this, he opens the window and points a giant fan out to circulate air through the apartment. The fan sucks out the aroma of the meatloaf and blasts it directly at my apartment and into my open window(s). Every day, I smell meatloaf. Let me tell you, that gets old.
