Been there, done that. Twice:
We took one of our grandkids to lunch several weeks ago (no symptoms/no exposure/no nothing). The next DAY, enrolling in school he tested positive/asymptomatic - and never developed any symptoms. We quarantined for two weeks and then tested negative.
A couple of weeks later, our granddaughter's soon-to-be-father-in-law came down with symptoms and tested positive. Neither she nor her now-husband had been around him for at least a week prior, but we were compelled to quarantine once again. Two weeks went by. Nothing.
Both times, our quarantining was not for 'our' benefit - we were confident that our exposure was minimal to non-existent - but for the well-being of others we interacted with, it seemed the responsible thing to do.
Don't know about you guys, but I'm sick of this stuff. I fully understand and concede that it's necessary, but I'll be among the masses that celebrate when it's over.
In the meantime, we all need to do whatever's necessary to stay safe and considerate of others' potentially fragile exposure.
Regards
