You know what's funny?
Kids at your school are continually on top of each other during recess? Interesting. At my kid's school, they didn't have any footballs, etc. to play with, so they mostly just ran around or threw rocks. No dog piles. lolHave you seen how kids play? I get why they did. Kids have no concept of social distancing. So while outdoor risk is super low, it isn't when you are continually on top of each other.
And my second grader absolutely understands the concept of social distancing. It has been drilled into her head over the last year by pretty much every adult she interacts with...for better or worse.
