How come President Biden needs a mask when greeting the Nationals mascots but not for selfies?

Earlier this morning we told you that President Biden showed up at the annual congressional charity baseball game and, notably, was not wearing a mask:

Can someone please explain to us the science behind wearing a mask when meeting people with giant stuffed heads but not when socializing with hundreds of people?

So glad to see @POTUS at this year's #CongressionalBaseballGame. I'm counting on my awesome new good luck charm for the next many years to come🤞🏾! Let's gooooo! ⚾️🧢
