Not trying to be a jerk here Bob, have you even been in a school, during school hours and witnessed the “mask wearing”? It’s all a CYA thing for schools and health departments. The kids don’t wear the masks properly and the teachers are tired of enforcing. No one can come back in 10 years and sue someone successfully if they were attempting “best practices”.
The reason for all the “masking in schools keeps numbers low” only keeps numbers low because it makes it seem as though masks are working because the rules say I don’t have to quarantine if I have a mask on my chin. Watch a school bus when you pass one, kids are supposed to be wearing them on buses, they are, just not over their nose and mouth. I heard a story from an education buddy of a superintendent watching bus video to determine if a student was a close contact. The rule was 15 min next to each other. Well, that super timed the students in close proximity at 14 minutes and 30 seconds ?. Guess what, determined to NOT be a close contact because of 30 seconds. Just one example of humans playing with their own rules to suit their own outcomes. I’m sure there are countless other anecdotal evidence stories out there.
