[ExI] the CDC's weird recommendation on masks

Wed Mar 11 22:32:52 UTC 2020

I'm surprised to hear that.  I would expect everyone to follow that these
days.   The good thing is that all of the kids, at least in my area, have

mess.   You may want to make them aware of the elbow bump which is now de
riguer to replace the handshake :-).
