Nothing will happen. We'll all get up in the morning, maybe eat some breakfast, go to work, come home, play with the kids, eat some dinner, may shag your wife/husband, go to bed. Repeat. I can't wait for four years to fly and be just as boring as the last four years.
Actually, maybe that's what life will be like for a white, upper middle class, cisgender-heterosexual married male in his late 30s-40s, but for anyone who isn't that... oh boy are we fucked.
