Well..it seems to be about a couple who love each other, but at the same time resent each other. I initially thought it was about Cobain's parents and the breakdown of their marriage, but the couple are described as traveling hippys, who sell arts and crafts at a market (swap meet). Cobains parents were not hippys..they were fairly conservative, so maybe it is about his parents, but he describes a fictional couple to be more subtle? just a guess..
