First, I am not blase, I am a realist. You can't put 40,000 18-22 year olds together in a town, and not expect a virus to do virus things. And you can't expect 18-22 year olds to not do 18-22 year old things. Anyone who expected any other outcome had their head in the sand.
From your reply, it sounds as if you have an 86-year old and a college aged son or daughter. I assume that you are keeping the two apart, protecting your at-risk 86-year old, while letting your college aged child live their life. That's what I am doing. 2 kids in college, 92 and 90 year old mom and FIL. FIL came to visit, we sent the at-home son away for 2 weeks. FIL is gone as of this morning, son returning tonight, remote classes start tomorrow. FIL never left the house, said it was like a "resort" as my wife and I dotted on him, as we should.
