Describe symbolism in The Solace of Open Spaces by Gretel Ehrlich

In Chapter Nine, Ehrlich makes a comical comment about the care packages newlyweds often receive at a local courthouse. The packages are filled with things like Midol, disposable razors, soap, shaving cream and Kotex, and she refers to this "Pandora's box of grotesqueries" as being a bleak symbol of marriage and what the couple had to look forward to: "blood, pain, unwanted hair, headaches and dirt" .
