My roommate last year had a refrigerator by his desk - two feet across from my bed (small room in seven-person apartment). For a good two months whenever he opened it for a few seconds this awful smell would come wafting over to my side and linger there. (Since my 'bed' was just a mattress on the floor with my table-sized desk above, there was no way for the smell to 'rise') After weeks of telling him he's got to clean that thing out, I opened it up one day and showed him the milk that had been sitting there since before Christmas. Turns out he didn't know milk expires.
