Not all smells - that would take a while.
OK, so last week Paul was away and I didn't know when garbage day was and now there's a bag of garbage lurking in the kitchen, waiting to be taken out. There are smells hiding in this bag and sometimes when I am nearby they ambush my nose in an unpleasant manner. Plus, last week was kind of rainy and cold, so I closed all of the windows in the apartment as a survival tactic, resulting in a buildup of 'man smell' in my room. The apartment, in short, was not an olfactory symphony. It was more like... nostril muzak.
