You don't have to kiss anyone on New Year's Eve. Seriously, don't just kiss any fellow partygoer to kiss somebody.
But think of it this way: Do you want to celebrate the new year by tonguing the food membrane of your friend's cousin, who wears a Monster energy drink hat and responds to nearly everything with "That's what she said"?
Besides, you know it's flu season, right?
And even if a literal virus doesn't find a way to cling to you, that rando just might.
Overall, you can do better than Frenching someone you don't know to ring in the new year.
