Ben Rothenberg has decided to be the mask police at French Open. The reply from Jelena is pretty funny. I think they're both out to lunch, to be honest. People who are interacting in their group privately really have no reason to wear a mask besides public display of solidarity especially since they are separated from others in an outdoor environment. At the same time, Novak's brother having a mask exemption is interesting because even my COPD/ILD patients on home oxygen can wear one without any troubles.
