I read in the BS section that
somebody had Jewish Christmas in July, how nice!

Which means:
The tradition at Christmas, for
New York Jewish-Americans, is to dine at a Chinese restaurant.
And go to the cinema.

So a Mudcatter in the Southern Hemisphere, where
they also have social-distance and beware of COVID-19,
dined out at a Chinese restaurant for the first time
in lo! these many months.
