I'd Rather Not

Yeah, uhh, no.

When someone would rather not, they don't want to deal with someone else or something. They may show this by turning around and walking away, actively avoiding the problem, or more subtly decline the problem (likely a person who is offering them something they don't want like a friendship). Things that are Absolutely Disgusting more often than not get this treatment. If somebody encounters Utter Death suddenly, like seeing a giant bloodthirsty animal behind a door, they might slowly close the door and walk away shaken by complete fear.
