Incorrect you fucking idiot. She was getting tested to gain entry to a jazz festival or get on a plane. Not for the greater good...that concept means nothing to her.
Had she gotten a positive test, she would have found a way to fake her way in. She is all about her own self interest (I don't believe I need to explain the concept of self interest to the guy with the Monty Burns avatar who pleasures himself to Ayn Rand pictures and Gordon Gecko movie clips).
She might have later announced that she had Covid, but only if she saw an angle to make money off of it.
The party of "fuck your feelings" is really the party of whiny fragile people with their panties in a bunch.
