It’s a virtue signal. One of my friends posts selfies with a mask but pictures at get-togethers show everyone without a mask including them. Another friend has been Mask Karen from the get-go and he had to get tested and posted on FB “If we have been together in the last few days, you may want to quarantine” and I’m thinking “Why were you around a bunch of people if you think Covid is so serious?”
OMG! I have a friend that does the same thing! He said once, I am staying home to work and waiting for the vaccine. Then posts himself on Instagram at a pool party with a bunch of people taking pics hugging and swimming together. Hypocrites.
