"Onion rings in the car cushions do not improve with time"

This quote by Erma Bombeck is an amusing way of saying that little issues or messes do not disappear by themselves, however rather tend to get worse gradually. The image of onion rings in cars and truck cushions is meant to be funny, however it also functions as a metaphor for any kind of mess or concern that is left unattended. Much like how onion rings would only become harder to clean the longer they are left in the car cushions, issues in our lives will just end up being more complicated and tough to solve if we neglect them. This quote acts as a tip to deal with and fix problems as soon as possible, rather than letting them stick around and potentially worsen.
