Our couch suddenly smells like B.O. It isn't really bad or really strong, but every once in a while a hint of B.O. wafts its way up to my nose. This isn't a huge problem for me because it is one of the commonly agreed-upon bad smells that I am very tolerant of, but I'm not sure how the rest of the household is going to react. For the past hour since I first noticed it, I've been going over in my mind who has recently sat here, and I've not come to any conclusion. The only people who have used the couch in the past 24 hours are people who I'm familiar with, and who have used the couch before without incident. This leads me to believe that either some person was having an uncharacteristically smelly day, or we have the ghost of a hobo haunting our living room, lying on our couch and eating beans out of a can.
That would explain why we have so much trouble with the can openers in our house.
