We had a trio of workers at our house yesterday who asked if we wanted them masked because they were unvaxxed. YES PLEASE (despite our vaccintated state). When I offered them the “30 second sales pitch” the leader told me that it was none of MY business, and anyway they’d already had it, had survived, and were now immune. I mentioned the Delta variant and was told they were waiting until they knew it was safe. I shrugged and backed off… but I think they’re self-centered ill-informed (at best) and unwilling to learn something outside their comfort zone.
