The day when the coronavirus began and took over (Also new years eve), a painful day in history that will be remembered. On December 31, everyone shall mourn the deaths of the Coronavirus's victims (If we're out of quarantine yet....). If your birthday is on December 31, well that's just sad.
Girl 1: YAY, IT'S NEW YEARS EVE!

Boy 1: ....No....today we mourn the victims of the Coronavirus........

Girl 1: Oh, but it's December 31, right?

Girl 2: SHHHHH....The fireworks for the mourning are about to happen
